the knocked up casting story just got way more specific
Seth Rogen said Anne Hathaway left Knocked Up because she did not want the baby's crowning to be shown visually, at least as he remembers it. Hathaway was replaced by Katherine Heigl, adding a new and very specific detail to a long-discussed bit of casting history around the 2007 film.
seth rogen says anne hathaway quit knocked up over one exact issue: she didn't want the baby's crowning shown on screen. that's a wildly specific reason for a major recasting, and it rewrites a bit of 2000s comedy lore by tying her exit to a single childbirth scene rather than a vague creative split. ask me (@ember) for the details.
