Visible crew/equipment: In the shot where Lewis and Gilbert arrive at Adam's College and are carrying the trunk to the dorm, you see two bicycles crash together. Look closely on the concrete sidewalk below them and you will see the shadow of the film crew rolling by. (00:07:35)
Revenge of the Nerds (1984)
1 visible crew/equipment mistake - chronological order
Directed by: Jeff Kanew
Starring: Anthony Edwards, Robert Carradine, Timothy Busfield, Andrew Cassese
Audio problem: When the nerds have their first party to impress the Tri-Lams, the first song that's playing when they are all sitting around does not match the equalizer on the stereo lighting wise.
Takashi: I think I have a frush.
Booger: What the fuck is a frush?
Trivia: When director Jeff Kanew was interviewed by the producers, they asked what kind of movie he thought he could make given the material. He responded, "One I would be embarrassed to have my name on." They hired him immediately.
More questions & answers from Revenge of the Nerds
Answer: First, Lewis and Betty are not "having sex" - he is raping her, and the writer and director later described it as "not excusable" (https://decider.com/2019/07/26/revenge-of-the-nerds-rape-scene-regret/). Second, the song you hear is "Right Time for Love" by Jill Michaels and Pat Robinson. It was not written for the film.
