Ben Stiller Talks Improvisation in 'The Watch'

Some of the most classic film moments have been improvised or were outtakes, and one can imagine that comedy films like The Watch don't always stick to the script. Ben Stiller revealed to ET how closely he and his co-stars followed the original script of the upcoming film. "There was a lot of improvisation in the movie," Stiller said. "The script was great and it was really funny, but you can't help [it] when you got guys like this where you just want to have some fun and liven it up." VIDEO: B
