In the game, toi can purchase movie & musique spheres at the theatre in Luca. The movie spheres are all of the FMV sequences toi have seen during the course of the game.
This is done best at the end of the game. All the spheres are very expensive so, I sold everything I had to purchase them all & saved the game in a file slot on the memory card that I only use to see & listen to those spheres.
If toi turn off Subtitles in your game configuration settings they won't appear in the FMV sequences.
If toi discover something new that unlocks another FMV sequence that too will be available as a movie sphere that toi can purchase.
