Knocked Up (2007)

Knocked Up is a 2007 American romantic comedy film from Universal Pictures written, co-produced, and directed by Judd Apatow. It stars Seth Rogen, Katherine Heigl, Paul Rudd and Leslie Mann. The movie follows the repercussions of a drunken one night stand between Rogen's slacker character and Heigl's just promoted media personality that results in an unintended pregnancy ("knocked up" is a chiefly North American slang expression for being pregnant, usually unexpectedly).
