Dana Carvey is actually an accomplished drummer, and did his own drumming in the film.

The club "Gasworks", where Wayne meets Cassandra, was named after an actual rock and heavy metal bar in Toronto - Mike Myers' home town - that featured live bands, and regrettably closed in 1993 after 25 years.

This film was shot in only 34 days, as both Dana and Mike had to get back to filming SNL.

The police officer in Stan Makita's Donut Shop is named Koharski, in reference to NHL Referee Don Koharksi. After poorly officiating game 3 of the 1988 playoff series between the Devils and Bruins, Devils coach Jim Shoenfeld and Koharsky argued on the way to the dressing rooms. Koharsky fell and told Shoenfeld he'd be suspended for pushing him, and that it was all on film. Shoenfeld said, "Good, cause you tripped and fell you fat pig, have another donut.". All this was shown on ESPN.

When Wayne plays "Stairway To Heaven" in the music shop, he is then stopped and says "No stairway". The filmmakers actually tried to get the song played in the movie but were denied, so this is just a little nudge at them in this scene. I think Mike Myers mentions this on the commentary on the DVD.

Stay past the credits for an extra scene.

Mike Myers actually played the first few notes of "Stairway to Heaven" in the theatrical release. The director's later found out that playing even a few notes of the song would require special permission from the band, which they did not have. As such, all VHS and DVD copies have been dubbed over with the ending riff to "We Will Rock You" by Queen. They sound similar, and the producers hoped viewers wouldn't know the difference.

Noah's commercial for Noah's Arcade has the video game "Sonic The Hedgehog" in the background, which was released on the Sega Genesis, and is not an "arcade" game. This is a deliberate pun as to just how clueless Noah Vanderhoff is to the video game market.

During the 'Terminator 2' parody scene with Robert Patrick as the T-1000 Terminator, the song "Time Machine" can be heard in the background. This song featured on Black Sabbath's 1992 album called "Dehumanizer" which featured a painted image of a Terminator Endoskeleton disguised in a grim reaper costume as the cover.

Wayne and Garth's hang out, Stan Mikita's, is a parody of the donut shop chain in Canada, Tim Horton's, which was started and named after the Hockey Hall Of Famer and former Toronto Maple Leaf.

After using Queen's "Bohemian Rhapsody" in the movie, it sent the song to #2 on the Billboard Singles chart, nearly 20 years after the song was released. The soundtrack to the film made it all the way to #1.
