Isabella Rossellini claims that during the initial filming of the ritualistic rape scene, David Lynch couldn't stop laughing off-screen at the weirdness of it all. Though she was baffled as to why he was laughing at the time, Rossellini says that to this day, she herself laughs uncontrollably every time she watches that particular scene.

In an interview, Dennis Hopper claimed that writer/director David Lynch would never say the word "fuck" during filming, he would simply point to the line in the script and say "that word". Hopper laughed, saying "He can write it, but he won't say it. He's a peculiar man." Lynch has said this isn't exactly true, but he didn't want to charge the atmosphere anymore than it already was.

In Jonathan Ross Presents for One Week Only: David Lynch (1990) Lynch claims that the robin in the final scene is a real bird. When told that it looks like an artificial bird, he says, "Well, it's playing a role" and smiles broadly.

Isabella Rossellini actually was naked under her velvet robe when she did the "ritualistic rape scene", a fact that her partner Dennis Hopper was not aware of until the cameras started rolling and his co-star opened her legs for him to kneel between. This scene was the very first time the two of them ever worked together.

Several of the actors who were considered for the role of Frank found the character too repulsive and intense. Dennis Hopper, by contrast, is reported to have exclaimed, "I've got to play Frank. Because I am Frank!"

Roy Orbison initially rejected David Lynch's request to use the song "In Dreams" in the brothel scene. Lynch found a way to legally use the song anyway and Orbison did not discover the song was in the movie until Orbison just happened to see the movie in a California theatre. Orbison eventually filmed a video for the song that was produced by Lynch with footage from the movie.

Isabella Rossellini's role was written by David Lynch for Debbie Harry. Harry, sick of receiving offers to play "the weirdo" after she had played such a character in Videodrome (1983), turned it down.

The film was the inspiration for Twin Peaks (1990).

The scene in which Jeffrey and Frank go driving off at breakneck speeds was filmed by having stagehands rock the (stationary) car while others ran past with lights in their hands.

The character of Frank was to breathe helium at various intervals in David Lynch's original script, but Dennis Hopper suggested this be changed to amyl nitrite which he knew was used to enhance sexual experiences. Hopper only realized years later how bizarre the concept of a helium-breathing maniac talking with a high voice was. Lynch, however, felt that using helium might elicit laughter in the audience which would have been undesirable.

Dean Stockwell held a worklight in the "In Dreams" sequence only after director David Lynch saw him holding one during a lighting session. He was originally supposed to hold a microphone.

Producer Dino De Laurentiis had to set up his own distribution company, D.E.G., in order to get the film into theaters, as nobody else was willing to touch it.

Molly Ringwald was originally offered role of Sandy, but her mother objected to her starring in it due to the graphic content of the film. Laura Dern was cast instead.

The role of Jeffrey was originally offered to Val Kilmer, who turned it down, describing the script he read as "pornography", although he says he would've done the version that finally made it to the screen.

A scene in which Dennis Hopper hits Isabella Rossellini was edited so that his hand connects with her face off-screen, to satisfy MPAA concerns about violence towards women. Director David Lynch opined that that change only made the scene more disturbing.

The producers did not want to pay the rights for including the original recording of Bobby Vinton's song "Blue Velvet". So Angelo Badalamenti was brought in to record a new version that sounded exactly like the old one. After Badalamenti delivered, the filmmakers invited Vinton into a studio to re-record vocals for his famous song. It had to be arranged two and a half keys lower because of Bobby's changed vocal range. David Lynch heard the new recording, liked it, but thought that it would not work as well as the original version and finally convinced the producers to shell out the extra money for using it.

The movie's line "Don't you fucking look at me!" was voted as the #74 of "The 100 Greatest Movie Lines" by Premiere in 2007.

In the original screenplay, the sex scene between Jeffrey and Dorothy was longer; Jeffrey spins the propeller on her son's hat when Dorothy undresses him and Jeffrey learns Frank is coming. Dorothy thinks Jeffrey is her husband Don and cries when saying Jeffrey's name.

David Lynch originally wanted Song to the Siren by This Mortal Coil playing when Jeffrey and Sandy are dancing in the bar because it was one of his all time favorite songs. Despite many efforts to obtain the rights, Lynch was not able to use the song. Despite his disappointment with this situation, Lynch was granted rights to the song for his later film Lost Highway (1997).

The prosthetic ear found by Kyle MacLachlan's character at the beginning of the film has remained in the possession of its creator and makeup supervisor Jeff Goodwin despite numerous claims to the contrary. The ear was originally modeled from Goodwin's own ear until Lynch remarked that it looked like a child's ear. It was then remodeled from Fred C. Caruso's ear.

Isabella Rossellini and Kyle MacLachlan went through improvisations of all their scenes together when they first met, the day Rossellini was testing for the role of Dorothy.

David Lynch had never seen any of Laura Dern's previous films. Isabella Rosellini had seen Mask, and was so convinced by her performance that she wondered why Lynch had cast a blind girl in a role that hadn't been written as such.

David Lynch initially envisioned Hanna Schygulla for the role of Dorothy. When she declined, he thought of Helen Mirren for the part, before meeting model Isabella Rossellini in a New York City restaurant.

Harry Dean Stanton was the first choice for the role of Frank but Stanton turned it down because he did not want to work on a violent film. He later appeared in works by Lynch several times, including The French as Seen by...: The Cowboy and the Frenchman (1988), Twin Peaks: Fire Walk with Me (1992), Hotel Room: Tricks (1993), Inland Empire (2006) and several episodes of Twin Peaks (2017).

Steven Berkoff was David Lynch's first choice for Frank Booth. When he rejected it the role went to Dennis Hopper. Berkoff said that "there was nothing in that part except destruction".

When Frank and his crew arrive with Jeffrey at the brothel, Frank announces "This is it". The neon sign in the window of the brothel says "This is it".

Chris Isaak was up for the role of Jeffrey Beaumont, but he turned it down and the role went to Kyle MacLachlan. David Lynch used two songs by Isaak from his 1985 debut album "Silvertone". Isaak later agreed to appear in Twin Peaks: Fire Walk with Me (1992) in a role, which curiously was originally intended to be another Kyle MacLachlan character, Agent Dale Cooper, until the role was re-written into two separate parts.

Premiere voted this movie as one of "The 25 Most Dangerous Movies".

The word "fuck" is used 56 times. All but once by Frank Booth.

During a 2018 interview with Alec Baldwin on Baldwin's WNYC radio program "Here's the Thing, " Kyle MacLachlan said that Blue Velvet had a pre-release test screening (then a common practice for studio films) in California's suburban San Fernando Valley. The test audience filled out comment cards after the screening, and, MacLachlan said, they were some of the worst response cards the studio had ever seen for any movie. MacLachlan remembered that everyone involved with the making of the film were despairing until the New Yorker film critic Pauline Kael reviewed the film and "explained it to people in a way, or pointed them in the right direction, or helped them to get a sense of what the world that they were seeing was about, and that started the slow movement of acceptance of the movie."

The second work in which Dennis Hopper plays a character named Frank. He would go on to play seven completely unrelated "Franks" throughout his career.

Jeffrey says "I'm in the middle of a mystery" exactly halfway through the film.

Dennis Hopper says "fuck" in nearly every sentence. He is also the only one to use the word in this film, except for Dean Stockwell who says it once (on command by Dennis Hopper's character).

David Lynch supposedly cut the film from its original four-hour running time to one frame short of two hours. Despite many searches, the missing two hours of deleted scenes were thought to be lost, until in early 2011 Lynch announced that some footage had been found. The 2011 Blu-ray release features 50 minutes of those deleted scenes. The newly found scenes include Jeffrey at a college party before his dad's heart attack where he witnesses and stops a potential date rape; a woman lighting her nipples on fire at the bar/brothel that Frank brings Dorothy and Jeffrey to; many more scenes inside the Beaumont household with the mother and aunt; Jeffrey having dinner at the Williams house; a conversation between Jeffrey and Dorothy wherein Dorothy brings Jeffrey up to the roof of her apartment followed by a lovemaking session, and many more. Numerous still photos from deleted scenes appeared on the 2002 special edition DVD release of the film, even some which do not appear on the 2011 Blu-ray. The missing scenes can also be read in the original screenplay of the film, including an original ending in which Dorothy commits suicide.

It was understood in the script, though not final film that Frank's kidnapping of Don Vallens, Dorothy's husband, resulted from drug trafficking. Don had been a dealer who tried to go clean and become a police informant, so his former traffickers called in Frank as a criminal enforcer. Frank became obsessed with Dorothy, kidnapping Don and their son as collateral, but when Dorothy became suicidal, Frank started torturing Don, cutting off his ear to keep Dorothy alive. Much of this material, including Dorothy's eroding mental state, appeared in the deleted portions of the film.

In interviews, David Lynch has told of how Dorothy's nude scene was inspired by a childhood memory of his, when he and his brother, going home from school, came across a dazed naked woman walking down the street. Lynch has said that it made him cry and left a profound impression on him. Besides the impact on his life of the naked lady, Lynch says that the image of a severed ear and the mood of Bobby Vinton's 'Blue Velvet' song were two other major inspirations.

In the scene where Jeffery askes his blind coworker how many fingers, and guess right, if you look closely you can see the blind man's companion very quickly tap his shoulder four times.

Among the deleted scenes that appeared on a 2011 25th Anniversary Blu-Ray edition were previously unseen scenes showing Jeffrey at college before he has to come home in the aftermath of his father's stroke. In these scenes, Jeffrey has a college girlfriend (who in the official cut of the movie went totally unmentioned) who was played by Megan Mullally, an actress who many years later became famous for playing "Karen" on the sitcom Will & Grace (1998).

Sandy telling Jeffrey about her dream about robins is a strong foreshadowing of the ending scene which Jeffrey, Sandy and Aunt Barbara witnessing a robin eating a beetle and that the robin eating the bug represents love conquering evil and love can triumphant over evil.

After the "rape scene", when Dorothy goes into her bathroom and stands next to the sink, Jeffrey looks down at the floor. Instead of seeing her blood or urine on the floor, Jeffrey notices there's a swatch of blue cloth ripped out of the hem of Dorothy's robe.

One of the most powerful scenes in the movie the sex scene between Dorothy and Jeffrey (1 hour/ 8 minutes into the movie) depicts the main protagonist (Jeffrey) succumbing to his dark side.

In the narrative in the scene which Jeffrey is crying after he is beaten up by Frank: Jeffrey is crying because he realizes he is becoming like Frank Booth and that he is succumbing to his dark side when he had sex with Dorothy and hitting her.

Although Dorothy's husband Don Vallens is portrayed by Dick Green severed ear was not modeled after Green's one, but from that of film's producer Fred C. Caruso. Makeup supervisor Jeff Goodwin originally molded a few versions after his own ears, but David Lynch rejected them because they were small and looked like those of a child.
