A pre-oscar winning Jonah Hill stars in this massively successful 2007 comedy, playing a semi-fictionalised version of Seth Rogen, who wrote the screenplay with Evan Goldberg, whose alter-ego is played by go-to geek Michael Cera. The story is familiar - a quest for booze to bring to object of affection's cool party that doesn't go quite to plan - but the laughs come fast and hard and the core message is actually quite sweet. It hasn't become a cult classic for nothing.
