Mine would have to be the end of Fight Club when Helena Bonham Carter and Edward Norton hold hands while watching the world around them collapse. The Pixies were perfect for that scene!
the "I will find you, and I will kill you" scene from Taken. Liam Neeson was awesome in that film!
Either t
The scene in Pink Flamingos when Crackers brings a girl home. He takes her to the chicken house where he rips the head off a chicken (it was lunch for the cast later) and shoves it between them as they have sex. It flaps it's wings and bleeds all over the place as Crackers screams "fuck that chicken! Fuck that chicken!"
If I had to pick just one I would go with the "Singin' in the
Rain" number from the movie of the same name.
