Eternal Sunshine of the Spotless Mind
Absence makes the heart grow fonder... unless you're Jim Carrey in the movie Eternal Sunshine of the Spotless Mind. In one scene, he was about to start shooting a part where his girlfriend disappears but wasn't told she would no longer be in the shot. The look of confusion on his face was genuine as he kept trying to figure out where the costar had gone and why she wasn't on time!
