The Crow (1994)

There are so many great ones, but the one I think would be irreplaceable is dances with wolves.

Choosing is too difficult, it all depends on your mood in a given moment.

Some favourite OSTs:

• 2001: A Space Odyssey
• Blade Runner
• Ghost in the Shell 1/2
• Pulp Fiction
• Scarface
• Trainspotting
• Six-String Samurai
• Nausicaa of the Valley of the Wind
• The Matrix
• The Terminator
• City of God / Cidade de Deus
• StrayDog: Kerberos Panzer Cops / Keruberosu: Jigoku no Banken
• Guest from the Future / Gostya iz budushchego (technically a mini-series)
• The Irony of Fate, or Enjoy Your Bath! / Ironiya Sudbi, ili si Lehkim Parom

Gladiator is definitely up there. That or LOTR

A Clockwork Orange

That Daft Punk Tron: Legacy soundtrack.

Le Fabuleux Destin d’Amélie Poulain. Also my favourite movie.
