Favorite scene?
Mine was when George Clooney gets paranoid at the park and all the routine exercises seem like calls to the CIA to him and his plain-dumb expression.
Second was when Brad Pitt goes to negotiate with John Malkovich and he comes in a bicycle and John Malkovich's expression and the conversation in the car.
Even the part where Frances McDormand keeps taking guys to watch that rom-com was funny!
