Plenty..but here are a few which I can quickly think of...
1. The Godfather: Don Corleone visits Bonasera and asks him to "fix" Sonny's dead body.."Look how they massacred my boy..." Unforgettable!!
2. Fight Club: The scene in which Tyler gives the narrator a "Chemical Burn"!
3. Mulholland Drive: The Castigliane Brothers..Espresso scene.."This is the girl!"... Outstanding!!
4. Lost Highway: "We've met before, haven't we?" Mystery man briefly interacts with Fred Madison...this scene always sends shivers down my spine everytime I see it!
Al Pacino, Robert De Niro, Mickey Rourke, Edward Norton, George C. Scott
