clearly there is some legal mess which prevents the thing from happening
That is wrong, actually, from what I've heard. Allegedly what happened was someone at Marvel (Ike Perlmutter I think?) was trying to kill off the X-men and Fantastic Four franchises, because Marvel didn't own the movie rights to them. Reasoning being I guess that they'd rather see the characters die off than boost franchises which would also drive profit for competitors. There might be a business case to be made, but what I'd heard made it seem like it was much more about spite.
There's been a change in management recently, and it seems like they're willing to start using those characters again even though they still don't have the movie rights.
