1. Feige said never say never when it comes to Fox and Marvel making a deal anything is possible.

Lauren Shuler Donner: I would love it. I would love it. I personally have close ties to Marvel because of Kevin Feige, because Kevin worked for me. But to take our characters and mingle them in the way that they were written, yeah, absolutely.

Feige also revealed that their are contingency plans when Marvel gets the right to use certain characters whether in a deal, or full reversion now why would he reveal such a thing if a deal wasn't in talks or on the table in the first place.
