It is hard for me to pick a favorite, but I like action and adventure films. As well as spy thrillers with complex plots.
However, my favorite opening to a film would have to be the one to Cutthroat Island
Here is it with isolated score. Perun Almighty! I love the music!
The film was a major flop and hence fell into obscurity, but I highly recommend it. It is much better than the Pirates of the Carribbean movies.
