Dirty Grandpa

A great spoof of the 1967 poster for The Graduate substituting Ann Bancroft's leg for Robert De Niro's.

I Was a Teenage Wereskunk

An homage to 50s monster movies with a silly premise gets an appropriately silly and hilarious poster. Great tagline too!

Keanu

A gangsta cat with plenty of bling and attitude to spare makes the purrfect poster.

Office Christmas Party

Imagine being the cleaning staff facing this first thing in the morning. The aftermath of the party from hell. The still burning Christmas tree is an especially nice touch.

Why Him?

Sometimes a photo is all you need for a great poster. The dramatic contrast in expressions of the three characters sells the film's concept in hilarious fashion.
