Famous Movie Lines That Were Actually Improvised

Knocked Up

Seth Rogen had toiled away in shows that were almost hits, such as Freaks and Geeks until he really struck gold by pairing with Judd Apatow for films such as Knocked Up.

Apatow practically created a new style of comedy where improvisational jokes were the expectation, not the exception.

As a result, there are tons of great jokes that Rogen came up with on the spot, including the hilarious one about the film Munich.
