The only hope now is that Fox does what Sony did, and works out a sharing deal where they "keep" the rights, but Marvel gets its fingers in the pie too. That way everybody wins!
Oh, and by the way: Josh Trank's claim that he had a good version we'll never get to see? It might be true. Collider shared some gossip about the production:
I've got a source, fairly close to the production of this film, who had told me that the movie that Josh Trank and Fox had agreed on making - included three really big action set pieces. That was all agreed upon, it was part of the flow of the movie. And a movie is like a puzzle, you have all the pieces in place. You start messing with pieces and suddenly the whole puzzle can look out of whack. And they had agreed upon this vision for a film. And days before production began, Fox came in and made him pull three main action sequences out of the film. I was also told, the ending of the film was not even Josh Trank's. At some point they hijacked the editing bay from him. To the point that the editing of the film was done without him.
So why is Fox so desperate to hold onto this license, again?
