The plot of this wacky R-rated comedy isn’t the most original one, but its execution is absolute aces. After a young couple (Seth Rogen, Rose Byrne) with a baby move into a house, they discover that a rowdy college frat, run by Zac Efron and Dave Franco, has taken over the place next door. Soon, the two parties find themselves swept up in a no-holds-barred prank war. Directed by Nicholas Stoller (Forgetting Sarah Marshall), this high-octane comedy shouldn’t work as well as it does, but really hits you thanks to the hilarious script, zany pacing, and fully committed performances of Rogen, Byrne, and Efron, whose apparent cocaine troubles while filming only seemed to augment his character’s intensity. This may be the funniest comedy since Bridesmaids, and is a definite must-see.
