From Superbad director Judd Apatow, Knocked Up tests the commonly disputed idea that opposites attract. Allison Scott (Katherine Heigl) and Ben Stone's (Seth Rogen) lives could not be any different. Allison is a hard-working journalist and Ben is a slacker who only wants to party. When fate brings the two together at a nightclub, they end up partying hard, drinking way too much, and have a one-night stand. Several weeks later, Allison starts to experience pregnancy symptoms and quickly tells Ben that she is pregnant. The movie follows the two as they try to navigate their own awkward relationship as well as being first-time (unexpected) parents.
