I never saw the Killer Clowns movie but those masks reminds me of Tim Burton's clown drawings and paintings in the Art of Tim Burton book. Tim Burton's clown art looks a lot like that and Burton's description "I grew up with a fascination for people that were dangerous. Why a fascination with clowns? Why do I like clowns so much? Why are they so powerful to children? Probably because they are dangerous. That kind of danger is really what it’s all about. It’s that kind of stuff that I think gets you through life. Those are the only things worth expressing, in some ways: danger and presenting subversive subject matter in a fun way."
