My personal favorites:
1. Bar scene, fade to Paris flashback, Casablanca
2. Valera saves Conan, Conan kills Rexor, Conan the Barbarian
3. Luke defeats Vader/Vader kills the Emperor, Return of the Jedi
4. Preparation for Fort Wagner assault/Give 'em hell, 54!, Glory
5. Kirk returns fire on the Reliant/Here it comes - Star Trek II
I'm not mean; I just don't like you.
