Pull the plug? Not likely! I'm sure that Disneys' lawyers have this wrapped up tighter than Dicks' hatband. His advice and input would be helpful, probably invaluable, but Pandora goes forward with or without him. It's kind of like Harry Potter. Uni could not have outbid Disney had Disney really wanted to have Potter. But Rowling insisted on the final say...on everything! Disney bid to the point they were willing to put up with Rowling. When the price went above that ceiling, they stopped. I don't know but, given that, I can't see them giving Cameron all that much control. And, certainly, not enough to pull the plug.
