If it's happening when movie files are supposed to play, then this sounds like a driver issue. If it happens more or less randomly then it could be a corrupted download.
Make sure that all your drivers are up to date and then fully power down your device (not restart! Full power down!) and turn it back on again. If that doesn't work, try redownloading the game and - if you're on PC - make sure to extract it to a fresh location.
