In Halo multiplayer, people who are not on the same team cannot share a vehicle like the Warthog jeep. The scene in which Simmons (Maroon colored armor) jumps into the Warthog driven by Grif (Orange colored armor) was shot with each character entering the warthog at different times. The "Camera" remained in the same spot and the two clips were spliced together, each filling about half of the screen, in post-production.

The character of Caboose (blue armor) was originally not supposed to be "the stupid one". He was essentially a mere counterpoint to the Red Team getting their own 'Rookie' Originally designed with only a hint of smarminess or chauvanisticness, the creators realized that the fans were commenting more on Caboose's "stupid" comments than anything else. Caboose is now considered by some to be the most popular character in the series.

The show's production company is called Rooster Teeth, which is another way of saying "cockbite", an insult commonly used on the show.

Geoff Ramsey, who voices Grif, is the only person involved in the show who has actual military experience - he served in the Army for 5 years.

At the end of episode six, Church and Tucker hide behind a rock to avoid the fire from the Warthog's gun, remarking "That thing's gotta run out of bullets some time". At the beginning of the next episode they are still waiting there, still being fired on, and say "Doesn't that thing ever run out of bullets?". This is a reference to the fact that in the game Halo, the vehicle-mounted guns magically never run out of ammunition.

Produced using the Halo and Halo 2 game engines. Almost all the scenes shown were done exclusively with the Xbox versions of Halo and Halo 2. Other games used include the PC port of Halo (for close ups of characters) and the PC Port of Marathon 2 (for scenes of Church in the past).

When Lopez "destroys" the Warthog to avoid being run over, it is clear that there are 2 explosions, not one. This is an example of "Warthog Jumping", which is a small bug in the physics engine of Halo, allowing a player to explode many grenades at once, causing a vehicle to fly into the air.

The Spanish spoken by Lopez is frequently incorrect, usually by misusing articles or mixing up the order of the words in a sentence. This is because lines written for Lopez were translated.from English to Spanish through Babblefish. The most usual errors are in the translation of some English expressions done word by word, instead of using some Spanish expression with the same meaning. That causes the fact that sometimes the sentences in Spanish have no meaning at all. This is also true of the occasionally-spoken French.

After receiving many emails from fans complaining about the excessive swearing in Season 1, the show's producers decided to tone down the language for Season 2, even going so far as to bleep out the F-word. When fans responded by sending them even more emails complaining about the lack of swear words, the producers responded by creating the foul-mouthed version of Church that is encountered in Caboose's mind.

The show was originally intended to have a short run of about 10 episodes, and to focus mainly on the Red Team, with the Blue Team existing mainly to observe and comment on the action from their base. However, the show's creators weren't able to work many of their planned jokes (such as Donut's pink armor) into the early episodes, so the show was expanded into what eventually became a four-year, 100-episode run.

During the deleted scene in which Church screams from within Caboose's mind, Morse code is played to imply O'Malley's escape. This Morse code is a repeated "cockbites", a common insult in the series.

To accomplish the task of getting the tank onto one of the bases, the producers first attempted to have 5 characters fire at the tank at once. When this didn't work, they managed to succeed by "Warthog jumping" the tank onto the base.

The Blue Team controls "Blood Gulch Outpost Alpha", whereas the Red Team controls "Blood Gulch Outpost Number 1".

During the Mother's Day PSA, Sarge gives a list of suggested items to give to your mother as a gift. The list is as follows: Extra-Bendy Cactus Exotic Flightless Bird Undercarriage Washer Dispenser of Goodies Yoga-tizing Spatula Mutant Goblin Argentine Man-Servant Space Goo (or similar) Fractal Misnomer Rhinoplasty Donkeyplasty Nastyplasty Old Shoe Horn Old Horn New Shoe Smaller Crawdads Sandbox (with box) Transparent Ding-Gong Articulated Thing Round One (or likewise) Extras Candy (with tips) Sonambulent Honkie Misguided Dobro Banjo Spaceship Parachutes and Fishes Tu Blave Macchu Pisshu Most Postacio Mustafa Portencio Claven (sans nuts) Shanks (all types) Wind Samples Mutton Extraordinary Slorf FineriesIt should be noted, however, that each entry is shown twice during the list.

The first scene of Season 1 was accomplished by placing the "Camera Man Character" on the gun barrel of the Tank vehicle and slowly rising it upwards. This had to be done slowly, else the game would "kill" the Camera Man.

Caboose (Blue Team) is actually looking at his own base when told to watch the Red Base late in the series. This was an intentional joke, but was completely ignored when the episode was released.

If a character in Halo is idle for a period of time, the hands on-screen fiddle with the gun the character is holding. Because of the requirement of keeping the "cameraman" character moving to avoid this, the producers considered adding the Camera Man character as an actual character. This was dropped when producers realized that adding black bars to the top and bottom was more acceptable.

In episode 49, the scene of Church in the past was shot using the open-source PC-port of Bungie's (the makers of Halo and Halo 2) first video game "Marathon".

The "I'm coming out with the Warthog" scene was done by setting a character's respawn rate (how long it takes for him to return after dying) high enough that the game would allow the player to watch other characters. This is one of the few shots where the Camera Man's targeting reticle is not visible - because in the game, he was "dead". This technique is also used for the overhead view of the Blues in episode 1 and the Reds at the beginning of episode 2.

One episode was almost released to the public, without the black bars on the top and bottom of the video. Without these videos, all the game-centric information would be exposed.

Originally, the character Tex was going to be named either Dex or Merc. The name Dex or Dexter is a common name used for creator Burnie Burns as he uses this name in a lot of his features. In the end, the first name of the character Grif was revealed to be Dexter. This information was revealed in an audio commentary by the cast, of Episode 0 and 1, which was only released to the public when Grif introduces himself as Dexter Grif in one of the PSAs

During its 50th episode, almost every memorable joke or event during the course of the first three seasons, especially the first, is revealed to be caused by a character time traveling and accidentally causing these events to occur in the first place. Episodes 51 and 52 focused mostly on seasons 2 and 3 events respectively, with the latter explaining how Church eventually gave up on stopping the bomb and went to Zanzibar.

In Episode #54, "Hello, My Name Is Andrew", it is revealed that Pvt. Tucker's first name is Lavernius.

In episode 28, Sarge and Simmons attempt to run over Lopez with the Warthog, mistaking him for a Blue soldier and then tried to run over Lopez. Right before this, Lopez rants to Tucker and Caboose about the day being known as the day he shall be victorious. At this moment, and as the Warthog moves toward Lopez later, we see through his eyes. At first, we see a directives screen which in the audio commentary is told to be a RoboCop reference. Lopez's "Prime Objectives" (Hate the Orange One, Fix Everything, and Call Mom More Often) are based on RoboCop's "Prime Directives."

The final episode was released with three different endings to the series.

The "fade away" effect used when Sarge is saved from death, and forced from the Faded Spirit World, was done by having the Camera-Man character simply walking backwards over a small hill.

The only scenes from the single player section of Halo were the 3-second use of the Pelican dropship from the beginning of Halo's "Silent Cartographer" level and the shot of the Master Chief's cryo tube as well as any shots of the character Vic are from the "Pillar of Autumn" level. In the game, the Pelican is only on the screen for a few moments, so the designers simply looped this momentary scene for its inclusion in the episode. Also a clip from the end of the game where Halo is destroyed is used in several episodes in season 3.

The creators have tried to end the series several times, but due to fan outcry and support the series continues on to this day. Creator Burnie Burns stated "We'll keep making (Red Vs. Blue) as long as people keep watching." The series is on its 14th season and has gone on to be the longest running web series, at over 14 years since the series began.

In one of the PSAs for Red vs Blue, there is a point-counterpoint of "Should You Get a Tattoo?" Church is saying no, and Griff is saying yes. Griff's voice actor, Geoff Ramsey, has tattoos all over his body. Burnie Burns, who voices Church, has none.

In the second episode of season 3, episode 40, Sarge remarks "Great Gustavo!" at the events going on. This is a reference to the name of the voice actor for Simmons, Gustavo 'Gus' Sorola, whose character then appears immediately after Sarge completes the rest of the line.

_Ed Robertson_, lead vocals of Barenaked Ladies, was asked to voice the character of Captain Butch Flowers, for the 50th episode.

The "AI implantation process" Tex refers to uses the opening scenes from Halo.

Starting in episode 46 in season 3, the weapon reticules (the circular targets which corresponded with pistols and the rectangular targets in episodes 43, 44, and 45) were effectively removed from the series. As explained on the forums, this was done by filming the series in "Oddball" rules, and giving the cameraman in the game the "Plasma Pistol" weapon. "Oddball" involves a character switching his weapon for a ball-like object. The makers found that if the cameraman had this certain weapon and were to hold a combination of the buttons to pick up the Oddball, switch weapons, and drop the Oddball, all at the same time, he would drop his weapon but be able to move away from the Oddball so that he would end up empty-handed. Thus, having no weapons, the cameraman automatically had no reticule, and the biggest bonus to the makers of the series, no weapons means no idle reloading animation that had created problems while filming in the past.

In episode 49, when Caboose is listening to Church's transmission from the past the "computer" that he was using had a Windows 9x (95/98/ME) style Blue Screen of Death. This is actually in the Halo 2 game, when the computer is activated to open a door, it says: "WAC A total FU exception has occured at your location. All system functionality will be terminated. Press any key to power cycle the system. If system does not restart; scream at top of lungs and pound on keypad. If you need to talk to a programmer press any other key. Press any key to continue."

When the series was started proper, there was "Episode 0", featuring certain characters in the series. One of these characters was Tex, who was using a camouflaging device at one point. Despite the fact that the character would not be in the early episodes, many people believed they saw Tex many times early in the series, using this camouflaging device. Fans went especially crazy when Lopez, a brown character, was standing in the far background against a dark brown wall, not part of the scene. During the time the camera was faced that it could see him, Lopez moved a little, and all most viewers could see was some sort of movement near the wall, but could not see a character itself. They assumed this was Tex, but it was cleared up in an audio commentary for the DVD.

In Episode 59 when Sarge is saying the Sniping order, Simmons asks doesn't that mean you go twice as much or ten times as much? Actually Sarge goes 2.7 times more then Donut and Simmons.

To create the illusion that the characters had their hands at their sides, the producers had to make each character look downward. This caused the player model's gun to point downward, while keeping the head facing upward. This bug in Halo 1 was fixed in the sequel, but a feature was added that players could lower their guns slightly so that for use in machinima so that it did not look like the characters were preparing to shoot each other. Although they used pistols again in a PSA video, the RvB team generally gave their characters SMG's in Halo 2.

As of the end of season 3, the only shots used from Halo: Custom Edition for the PC are: Blue Command in episode 10, Vic all through seasons 2 and 3, close ups of characters for O'Malley dialog in the second season as well as the April Fool's episode (numbered 28.5), O'Malley leaving Caboose's mind in episode 34 (a deleted scene on the DVD), and the new intro shot for the season 3 DVD. According to Burnie Burns, "The problem [with the Custom Edition] becomes that you need a computer for each character."
