“Hey Malkovich, Think Fast!” (Being John Malkovich)

Being John Malkovich is a fairly weird movie about a man who discovers a portal that allows him to literally get inside John Malkovich’s head. In one of the most memorable scenes in the film, Malkovich is walking down the street when he hears “Hey Malkovich, think fast!” and gets violently hit by a can.

The unscripted moment made it to the movie because it was good cinema! It was nothing but the work of a drunken extra, though, who wanted to make an impact. Instead of being fired, the man received an acting credit. After all, he was “given” one of the most memorable lines in the film.
