- Box Office Bomb: Budget, $40 million. Box office, $14.4 million.
- Creative Differences:
- Ivan Reitman was originally set to direct the film, but when he and Chevy Chase couldn't agree on the tone, Reitman demanded the studio choose either he or Chase. They chose Chase.
- William Goldman originally wrote several drafts of the screenplay, all of which were rejected, as he wrote it as a simple comedy, and the producers preferred to use the film to "explore the loneliness of invisibility". Eventually, he left the project, though he still receives a screenplay credit. He claimed never to have seen the movie, and thus cannot say for sure how much of his material is actually in the film.
- Even eventual director John Carpenter suffered a bit, as he wanted to focus on the comedic aspects, but Chevy Chase insisted on playing it mostly serious.
- Dyeing for Your Art: Chevy Chase got into shape for the role, working out and losing 20 pounds. Helps he had to at times get covered in full-body green\blue suits to make himself invisible - the worst being the scene where he's made-up to become visible, as Chase had to even wear uncomfortable lenses, and suffer through the heat (his costume, the June weather, the studio lights).
- Tom Hanks Syndrome: Attempted by Chevy Chase in the film here, who only gets a couple of one-liners, no more than any other actor would expect. It didn't work out so well for him, though.
- Wag the Director: The project was largely a Vanity Project shepherded by Chevy Chase through the studio. He found William Goldman's script too comedic, "Clark Griswold becoming invisible", and sought screenwriters to rework it, reportedly to do something "more serious, with more adventure".
- John Carpenter would go on to say that the production of the film was very troubling and vigorous. While also battling studio executives, Carpenter claimed Chase and Daryl Hannah were "the stuff of nightmares" and "impossible to direct". In particular, Chase would often refuse to wear his special effects makeup and would remove it prematurely, ruining a days-worth of filming.
