Knocked Up is a 2007 American romantic comedy film written, directed, and co-produced by Judd Apatow, and starring Seth Rogen, Katherine Heigl, Paul Rudd, and Leslie Mann. It follows the repercussions of a drunken one-night stand between a slacker and a just-promoted media personality that results in an unintended pregnancy. Using only the above description and what you know about the world, "Knocked Up was writted by Seth Rogen." is definitely correct, incorrect, or inconclusive?
