The Hangover
The Hangover was a great comedy film and the cast helped cement this status. Zach Galifianakis, in particular, delivered some of the best parts off the cuff. This includes the moment he did something scandalous to the infant. The actor talked about it with regret, however: “The one improv that will haunt me for the rest of my life, is the [scene where I] make the baby [unknowingly mimic a sexual act].” It’s a good thing it was only actually a doll!

Shaun of the Dead
Shaun of the Dead is definitely a great comedy film. However, fans might be surprised to learn that plenty of it was improvised. As an example, let us take a look at the pub scene when Ed consoles Shaun by telling stories about his regulars. Yep, it was all ad-libbed!
