I really feel sorry for the screenwriters who have to come up with a script for these movies. Can you just imagine you're a studio screenwriter and your boss comes to your desk and says that you have to come up with a script for Pez the movie.
Unless there is some great story behind the guy who invented it, this is beyond stupid.
The story behind PEZ is interesting, if not movie worthy https://en.wikipedia.org/wiki/Pez
But I highly doubt the movie is going to be some sort of bio-pic on the history of the PEZ candy and dispensers...
