I have a copy of Avatar in my brain. Admittedly, it's a bad copy- worse than the worst Russian screener out there. What can I legally do with my Avatar copy?

What if stood in a town square and vividly recreated the movie for a crowd of fans- using my brain-copy to make funny voices and pantomimes and such. Is that a breach of copyright?

I can imagine a future wherein you have to pay a subscription fee if you want to retain the copy of a movie in your brain- don't pay and the movie is scrubbed from your memory.

Copy-protection would be a neural block to prevent me from relating the story of a movie to friends:

"It was so awesome, first the ngyyayayaya!" (biting tongue and convulsing)
