There are a bunch,
- Batman 1989 (probably the Axis Chemicals scene). I pretty much destroyed the VHS from watching it so many times
- Star Wars and Empire, same as above. Rescuing Leia from the Death Star and the Bespin duel was probably my most watched scenes from both of them.
- The Terminator, Police Shootout and the surgery scene
- Robocop, Alex Murphy's death, ED-209, the factory shootout
- T2: Judgment Day, pretty much every scene. The galleria, Pescadero, Cyberdyne, the Steel Mill, pretty much all of it
- Die Hard, probably from "Bill Clay" to "shoot the glass" up until the climax/standoff with Hans
- The Fellowship of the Ring, definitely Moria and Amon Hen
- The Two Towers, Helms Deep
Way too many to count. I watched the Dark Knight a **** ton too, especially the Bank Robbery prologue and interrogation scene.
