In the desert scene, where Beavis and Butthead hallucinate, voices are heard in the background. When the soundtrack is played backwards, Beavis and Butthead are heard speaking clearly, including phrases such as "Everybody go to college, study hard, study hard."
In the DVD commentary, Mike Judge confesses that the guitar riff from Beavis and Butt-Head theme music is the riff from AC/DC's Gone Shootin' played backwards.
Mike Judge actually got the "is this a goddamn" joke from his grandmother, and when she told him it, he didn't find it funny at all. Ironically, numerous viewers have since told Judge it's their favorite part of the movie.
The white trash hoodlums that steal Beavis and Butt-Head's television are not unique to the movie. Their names are Ross and Harlan, and they previously appeared on the series robbing Stewart's house.
Broke the box-office record for an opening weekend in December, until Scream 2 (1997) was released the following year.
There's a line in the script that indicates that if President Bill Clinton lost his re-election campaign in 1996, there would be a change to the scene where Butt-head meets Chelsea Clinton. In the regular movie, she's folding clothes. But the scene was written so she could also be packing a suitcase instead with only a minor addition to the scene.
In the original cut, in the scene in which McVicker is being spanked in the motel room, he was naked from the waist down. The animators had to give him boxer shorts in order to get a PG-13 rating.
One of the people sitting in the circle when the teacher sings "Lesbian Seagull" is Daria Morgendorffer, who later got her own series.
After the success of the film, a sequel was planned to be released in 1999, but plans were eventually scrapped. Mike Judge has stated (as recently as 2019) that he is still interested in producing a sequel, though one is not in development.
When Beavis and Butt-Head try to steal the television from their school, and Mr. Van Driessen stops them, the Geffen Productions logo can be seen on the chalkboard in his classroom.
A reference to butane, made by Tom Anderson, was changed from propane to avoid a connection to Mike Judge's other animated series, King of the Hill (1997).
When the film was being envisioned as a live-action movie, the studio wanted Chris Farley and David Spade to play Beavis and Butt-Head.
The name David Letterman chose as his credit for his voice-work in the film, Earl Hofert, is actually the name of his uncle, the same "Uncle Earl" Letterman routinely mocks on his show, especially for an incident where a drunk Uncle Earl supposedly said "Here, kitty kitty kitty" to the Thanksgiving turkey.
Beavis's hallucination scene in the desert was inspired by artwork drawn by Rob Zombie. The music of the scene is White Zombie's "Ratfinks, Suicide Tanks and Cannibal Girls".
Siskel & Ebert gave the movie 2 thumbs up. Roger Ebert himself gave the movie 3 out of 4 stars and, in his review, said "Why is this movie so much fun?"
Major Beavis and Butt-Head characters that do not appear in the movie at all include Stewart (and his family), Coach Buzzcut, Todd, the Burger World manager, and the Maxi-Mart owner.
All of the hotel/casinos shown in the Las Vegas scenes actually exist. In contrast, Mike Judge's "more serious" show, King of the Hill, used fake hotel/casinos during a visit to Vegas.
Beavis and Butt-Head are never shown working their jobs at Burger World in the film, although this is briefly referenced during the hallucination scene.
Geffen Pictures acquired the film rights in 1993 with the hopes of making a live-action version of the series with David Spade as Beavis and Adam Sandler as Butt-head. Mike Judge hated the idea, finding the idea of making Beavis and Butt-head live-action not only sacrilege, but more expensive than animation. Reportedly, the decision to make the film in its final form was the result of a coin toss.
When Beavis and Butt-Head enter the church, there is an unintelligible chant in the background. If you listen closely, you can hear that the chant says, "Scrotum agitato, ignoramus, genitalius largus, hemmoridus burnum, all day long."
During the trek across the desert, the boys mention the 7-Eleven chain of convenience stores, a rare mention of a real-world store chain on the show.
Demi Moore and Bruce Willis were married at the time of filming. Their characters in this movie are also married to each other.
The version of "Walk on Water" on the official soundtrack is not the version that is heard in the movie. The version played in the movie is actually the 'demo' version, and it appears on Disc 2 of Ozzy Osbourne's 'Prince of Darkness' boxed set.
Robert Stack was so embarrassed to be associated with the film, that he paid a legal team to keep his name out of the promotional material. He eventually did warm to the role, however.
Daria appears, but doesn't have any lines. Other characters from the series that are absent from the movie are Stewart, Coach Buzzcut, and Todd, who is Beavis and Butt-head's "hero".
Hollywood director Mike Judge was a huge fan of Vijay Anand. Mike saw the film Double Cross,Tere Mere Sapne and Chor Chor and was amazed by Vijay Anand's westernized personality . When Mike directed Beavis and Butthead Do America, he animated character who looked like Vijay Anand. He appeared playing a guitar on stage during the song "Roller Coaster".
Bruce Willis who played Muddy Grimes, was married to Demi Moore who played Muddy Grimes' wife, Dallas Grimes at the time this movie came out.
