Mac and Me
Whether you see them or not, almost all classics have an unpopular spin-off. 'Mac and Me' was what took place about six years after E.T.: The Extra-Terrestrial smashed the box office. This version of the famous friendship grossed a pathetic $6 million in total, which was about half of the budget. Despite this, Paul Rudd lists it as one of his favorite flicks!
Masters of the Universe
'Masters of the Universe' was supposed to give fans of the He-Man franchise the movie they'd been asking for. To be fair, this is technically a movie, but no one was asking for it to be terrible! With a cramped schedule, a tiny budget, and not a lot of interest from studios to give it a fair chance, this highly anticipated superhero film was a beloved flop.
