We have some very short films:

There's a clip of me harrassing the old ID cards minister somewhere.
In terms of longer films, there's a More4 documentary called Suspect Nation I still haven't seen and you would need permission from the owner.
There's also Gattaca which is the kind of film you'd want to go see anyway. A Scanner Darkly has some interesting parallels and is becoming a cult film.
