1. Indiana Jones & Temple of Doom - John Williams. Perfect score for a perfect adventure film IMO
2. Total Recall - Jerry Goldsmith. Probably the best sci-fi score ever made.
3. The Untouchables - Ennio Morricone. Just listen the theme song.
4. The Living Daylights - John Barry. My favourite score from John Barry.
5. Quo Vadis - Miklos Rozsa. Beautiful and epic!
Other great composers that i like; Leonard Rosenman, Danny Elfman, James Horner, Max Steiner, Michael Kamen and Basil Poledouris.
