A-list director won't be cheap and i think it can reach hard cap without pouring money to an A-list director.
If the section where the movies are located is clearly explained... and the filmmakers agree with the fact that they can use it for publicity for their movies, and won't receive revenues (untill a certain rating or so) I don't see where this could go wrong.
I don't think an A-list director would accept that. If he is then he is welcome

But i expect him to ask a lot of money before accepting this deal.
