Zoolander
Can you imagine anyone else besides Ben Stiller playing the main character in Zoolander? Neither can we. The bit that gave the movie a spot on this list is the scene with the hand model in the graveyard. When the hand model (David Duchovny) delivers a monologue about why male models would be great assassins, Stiller erroneously asked why male models a second time. Luckily, David Duchovny decided to play along, dumbfounded that Stiller’s character didn’t register his whole spiel, and it looked absolutely seamless.
The Shining
We’ve talked about several Kubrick films by now, so let’s not forget about The Shining. Can you come up with anything more terrifying than watching Jack Nicholson’s character fall into madness? Let’s not forget the iconic “Here’s Johnny!” line as the character peers into the crack he just made in the bathroom. It was apparently improvised as a tribute to The Tonight Show with Johnny Carson.
