Revenge of the Nerds/Trivia
- Dawson Casting: Robert Carradine (Skolnick) and Curtis Armstrong (Booger) were thirty and thirty-one when the movie came out, playing eighteen year olds.
- Not to mention that the actor playing the Dean of the college is only two months older than Armstrong.
- Hey, It's That Guy!: Ted McGinley as Stan Gable, leader of the Alpha Betas.
- Danny from The West Wing as Poindexter.
- James Cromwell as Lewis' father.
- John Goodman as the football coach.
- Dr. Mark Greene as Gilbert.
- Reverse-Hey, It's That Guy!: Booger gets a literal Shout-Out (the music actually sings, "Hey, it's that guy!") in an "80s Montage" scene on a Progressive Commercial starring Flo.
- Lamar wants to own a fast food joint in space.
- Hey, It's That Voice!: Takashi would go on to voice the movie version of Leonardo.
- The Other Darrin: A pilot for a TV series was produced in 1991 and the returning characters were all recast. Rob Stone played Lewis, Lightfield Lewis was Gilbert, Grant Gelt was Harold and Jeff Benson was Ogre.
- Anthony Edwards did not return for the third movie, so he was played by Mike Greenwood in a one scene.
- Playing Against Type: John Goodman has almost always been associated with kind and affable Big Guys, here he plays the petty, cruel, and almost criminally negligent Coach Harris.
