Seth Rogen reflects on one day on the set of Knocked Up where multiple cast members actually vomited.

Knocked Up came out back in 2007. See what the stars of the hit movie are doing today!

Knocked Up, Judd Apatow's comedy about unexpected pregnancy, was a hysterical hit. We share offscreen trivia about the making of this Seth Rogen film.

Judd Apatow’s M.O. has always been to trick R-rated comedy audiences into watching movies that are sweeter, smarter, and more insightful than they were expecting. Knocked Up is a prime example of this, as we go in expecting a zany movie about a slacker man-child played by Seth Rogen getting a hot girl pregnant and having to deal with the consequences. But what we really get is a heartfelt examination of human relationships and the need to grow up. It’s an accurate representation of the reality of facing an unexpected pregnancy.
