Nope Fox has X-Men but not Scarlet as she ain't a part of that Franchise

Henry Pym would be cool but I have searched and searched and cannot find an ant-man movie mentioned anywhere. I have heard of a Namor movie and The Sub-Mariner was a villain and later a member of The Avengers.

No Fox fucked the X-Men franchise over with that last movie. There will be no fourth BUT we should be seeing a possible Wolverine movie

One thing is for sure, we will see an Avengers Movie, and if it is done even half as good as Iron Man it will rock because Iron Man is to date the quintessential Super-Hero movie, blowing any of the others away.
