Just out of curiosity... why can Roberto Orci, who is going to write the next script for a Star Trek movie, visit and engage in discussions on Trekmovie.com, when there are so many story ideas for the next movie thrown out by the fans? Yet in this forum it is not allowed to discuss story ideas, because the writers who are active members here could get in trouble, or at least some copyright issues might arise.
Is there a difference between copyright for "proper" literature and movie scripts?
