Being John Malkovich
The cult classic Being John Malkovich is rather trippy and completely original. It is thus easy to see how a random moment could have made it into the film. Remember when someone threw a can at Malkovich’s head and yelled, “Hey, Malkovich! Think fast!” Yeah, that was actually just an intoxicated extra who did it for kicks. Regardless, the director thought it was great and decided to put it into the final cut.
