Tom Ellis (Lucifer) does his own singing throughout the show, although does not play the piano on screen. In early interviews for the show, he said he didn't "really know" how to. In 2019, a video of him accompanying himself on a piano whilst singing showed he's since added this skill to his repertoire.

In almost all episodes, the name of the episode is said by Lucifer.

The book Chloe reads to Trixie is "Coraline" by Neil Gaiman. Lucifer is based on a character in Gaiman's "Sandman" graphic novels.

In the TV series Supernatural, season 11 Ep 10, the show's version of Lucifer says that if he got out of his cage in hell, he would move to LA and help solve crime. The episode aired before the Lucifer pilot.

After being cancelled on May 11, 2018 the Hashtag #saveLucifer started trending on Twitter and within a day on May 12, 2018 the hashtag has more than 1 million tweets. Currently on June 2, 2018 #saveLucifer now has more than 8 million tweets and counting.

VERY loosely based on the DC Comic character Lucifer Morningstar from the comic Sandman.

According to Tom Ellis, during his interview on the Rich Eisen show, the premise of the television show was born out of the pilot. Originally the series was going to be about Lucifer making deals with desperate/despicable people in order to collect favors from them on a later date. But after seeing how well the series work as a police procedural and the potential stories that could come from that, the series was revamped after the pilot.

Tom Ellis, Lauren German, and Aimee Garcia are all within 12 days of being the exact same age (November 17, 1978, November 29, 1978, November 28, 1978).

Apart from the pilot episode, the title of each episode is referenced at least once during its 45 minute airing.

At dramatically significant moments, especially throughout season 3, shots of Lucifer are framed so that background elements form the shape of wings behind him.

On 6/6/2019 Netflix announced that it renewed Lucifer for the fifth and final season. Co-showrunner Ildy Modrovich revealed season five will have ten episodes. On July 26, Netflix announced six more hours would be added, for a total of 16 episodes in season 5. Modrovich tweeted that the love of the fans helped to "supersize" the season.

According to the cast, the cast members most like their characters are Aimee Garcia (Ella) and Lesley-Ann Brandt (Maze).

The Lucifer cast and crew were told of the fifth and final season renewal only hours before the information was released to the public.

The show was canceled in its third season by Fox but was later picked up by Netflix for a fourth season.

Cheekily playing along with the Devil theme, Netflix announced the release date of Lucifer's fourth season exactly 666 hours before streaming availability began in the United States at midnight (PST) on May 8, by way of a teaser ad featuring Lucifer ( Tom Ellis ) emerging from a pool clad in only swim trunks, his ring, and a "666" tattoo.

In an amusing location choice for those who know Los Angeles, Lucifer's nightclub Lux is next to the El Capitan Theatre; in real life, the space is occupied by the Disney Soda Fountain.

In locksmith jargon, a 999 key refers to a master key or one that opens a specific series of locks. However, in the LAPD, a 999 key refers to a key issued to LAPD officers and some civilian employees that opens the employee (rear) entrance to all LAPD stations. All of the keys are identical, open every station's rear door, and are not individually serialized, or traceable to a specific employee or vehicle.

This show shares several aspects with Supernatural. One of which is the term of endearment, "Luci", which is sometimes used to refer to Lucifer.

Kevin Alejandro replaced Nicholas Gonzalez as Dan after the pilot was filmed. All of the scenes with Nicholas Gonzalez were then re-shot with Kevin Alejandro .

In episode 8 of season1 Lucifer: Et Tu, Doctor? (2016) Chloe says to Dan, "She conned you into reading the book about the sneezing panda, didn't she?" This is a reference to the children's book "Chu's Day" written by Neil Gaiman. Lucifer Morningstar is a character from "Sandman" also written by Gaiman.

Eve is frequently seen in the vicinity of, or has her coming appearances foreshadowed by, shades of apple green - appletinis, green background lighting, and, of course, literal green apples.

In many episodes, the Roosevelt Hotel can be seen. The Roosevelt Hotel is famous for being one of the most haunted hotels in Los Angeles. Some of the well-known ghosts are film stars: Montgomery Clift, Carole Lombard, Marilyn Monroe and Rudolph Valentino. KB351.

Lucifer is Dutch for "match", which also brings light.

In the pilot, there is a reference to Tom Kapinos' previous show Californication (2007). When Morningstar says that Trixie is a hooker name, it is a reference to the hooker named Trixie from Californication who is friended by that shows lead character Hank Moody.

Tom Ellis revealed on The Kelly Clarkson Show on October 28, 2019: "Season five is going to be split into two halves. Netflix is going to drop eight episodes, then there's going to be a little break, then another eight episodes."

Tom Ellis reprised his role as Lucifer Morningstar in The Flash: Crisis on Infinite Earths: Part Three (2019). That episode established that the series takes place on Earth-666, a reference to the Number of the Beast.

In season 1, episode 12: "#TeamLucifer", one of the prime suspects is named Mike Carey, which is also the name of the writer of the comics series.

Rachael Harris (Linda) and D.B. Woodside (Amenadiel) previously worked on the show Suits (2011) in seasons 2, 3 and 4.

Lina Esco was originally cast for the role of Maze, but the change was made after the pilot's table read, with Esco being released.

Season 4 features Graham McTavish, who plays Father Kinley. He's also featured in another show based on DC/Vertigo Comics, Preacher (2016), as the Saint of Killers.

Further connection to the myth of Persephone: "Chloe" is one of the many alternate names of the goddess Demeter, mother of Persephone.

Lucifer means "light bringer" in Latin, the place he runs - Lux also means "light"

Both DB Woodside and Rachel Harris starred together in Suits as the love interests of main characters but never shared a scene.

Despite being produced by Netflix Season 4 will still Air in Germany on Amazon Prime Video.

This is the 2nd time time Tricia Helfer plays a lawyer on tv. The first was in Suits (2011).

Tricia Helfer (Charlotte) and Lesley-Ann Brandt (Mazikeen) both had roles in The Librarians (2014), but never appeared together.

On June 23rd 2020 Netflix announced they were renewing the show for a sixth and final season.

5th would be its last season comprising of 16 episodes and divided in 2 parts of 8 each.

Halloween is the only major ¨holiday¨ shown in the entire series. Unusually for a major network series (but probably for obvious reasons, considering) there are no Christmas episodes.

Netflix have announced that Part 1 of Season 5 will drop Friday, August 21st, 2020.

Despite playing the Devil Tom Ellis revealed that his father uncle and sister are pastors and they're very supportive of his acting

The name of Lucifer's bar is "Lux" which is Latin for light, as well as the root of the name "Lucifer" (the light bearer).

The black convertible Lucifer is driving is a Chevrolet Corvette C1 from 1962.

The incidental music all references god, hell or the devil, although not always in the sampled section.

The wall of Charlotte Richards' (Lucifer's mother's host body) office prominently features three large paintings of pomegranates. Pomegranates are associated with the mythology of Persephone who must spend three months a year in the Underworld (winter). Pomegrates represent a connection to Hades (the Devil) and Hell.

In the original DC Vertigo comic the main characters' appearances differ greatly from the show. Maze (also called Mazikeen) is drawn with white skin and no flesh on half of her face (usually covered by a mask when in public). In season 2 of the show, Maze reveals her true face to Trixie, which is much like her comics appearance. Amenadiel is also white and appears much older (with white hair and a beard). And Lucifer himself was drawn, under strict instructions from Neil Gaiman, to look like David Bowie.

In season 4, Eve's clothing is in "apple" shades and reflects her involvement with Lucifer- first she wears white (symbolizing clean, pure) but has red shoes as a nod to him, then cream, then red with flowers, completely red, red with black... the darker the color the darker her relationship with Lucifer. The one (still symbolic) exception occurs in Lucifer: Who's da New King of Hell? (2019), when her dress is a deeper, almost violet, red with white spots.

In western culture it is proper to capitalize the word God as you would someone's name when referring specifically about God and not a god. Furthermore, pronouns used directly referencing Him are capitalized as well, as opposed to using him to reference another male. Lucifer follows this in the closed captioning, taking it one step further in that whenever he refers to Him, as Dad or Father or even Daddy, they are all capitalized. In the 2nd season, the main antagonist was his Mother, the Goddess, they continued this as well capitalizing Mum, Her and She, when she was referenced in conversation.

The paintings on the wall in Charlotte Richards's office are of pomegranates. Some scholars believe the pomegranate, rather than the apple, to be the real fruit from the tree of knowledge. Pomegranates also reference the Greek myth of Persephone, with Charlotte/Mum returning to the world of the living from Hell, while, like Persephone, being in some way unable to entirely escape it.

While the mystery of and reveal of Chloe's background are hugely significant plot points, nobody - including the chronically hyper alert about all-things-having-potentially-anything-to-do-with-his-dad Lucifer - seems to seriously question what this might mean regarding Trixie.

Prior to the arrival of Lucifer's mother, played by Tricia Helfer, Lucifer is playing "All Along the Watchtower" on the piano. Tricia Helfer played #6, a Cylon, on Battlestar Galactica (2004). "All Along the Watchtower" is the song that revealed the "Final Five" humanoid Cylons to one another.

Lucifer has yet to address or refer to Trixie by any version of her name.

In the first season, Lucifer explains that as the Devil, he has neither horns nor a tail. This is proven true in season four when his full devil form is revealed.

In the pilot episode, the song "Howlin' For You" by The Black Keys is played. Tricia Helfer who plays Charlotte (Lucifer's mum) starred as the main character in the music video. Although the connection would be unknown to viewers at the time as Helfer does not join the cast until season 2.

Further association with both Greek myth and "hellish" allegory: in the pilot, Trixie tells Lucifer her name is short for Beatrice. Beatrice is a character in Dante's Divine Comedy who sent the Poet Virgil to guide Dante through the nine circles of Hell. Beatrice was Dante's muse, his heavenly guide. Like Persephone, Beatrice became trapped in hell after consuming pomegranate seeds.

During the 2019 DC Universe Crisis on infinite Earths crossover event, it is revealed in The Flash: Crisis on Infinite Earths: Part Three (2019) that Lucifer, or at least the one on Earth-666, is aware of the existence of multiverses.

Besides Lucifer's literal wings, angelic references and imagery are scattered throughout season 3, both subtly and conspicuously. E.g. the Hotel Angelette in "They're Back, Aren't They?", St. Angeline Hospital in "Infernal Guinea Pig", culminating in a veritable volley of angels in "The Angel of San Bernadino" - angel figurines, "angelic visitatons", David Boreanaz (best known for playing a character named Angel in the Whedonverse) by way of an episode of Bones, as well as the word Angel in the very episode title, etc.
