I'm curious what you mean by Universal having the rights to those movies. The right to do what exactly? Spider-Man and Wolverine are already represented in IoA (one by way of a somewhat well known attraction, the other with a giant "cutout" just across the street).
If you mean the right to depict the movie versions of those characters in their parks, I guess I don't follow. The entire Marvel area of IoA is comic-based (no Hugh Jackman or Tobey Maguire, although if any theme park would have had the rights to those depictions, one would think it would have been Uni).
Also, is the implication that Disney could use a future Spider-Man for an attraction or a M&G in Florida, as long as it was specified that it was MOVIE Spider-Man and not the COMICS Spider-Man that IoA uses?
I hope this doesn't come off hectoring, but I'm really trying to make sense of what you're suggesting...and make sure I haven't missed a potentially big loophole in this Disney/Universal/Marvel drama!
I wish we knew the details of the contract Universal had with Marvel, so we could know how relevant Disney's ownership is for future re-ups. If it contains language that basically says Universal can have first dibs on the characters for all eternity barring some massive misuse of the properties, then Disney might be in the position of having no more power than rubber-stamping Universal's renewal.
On the other hand, if Marvel was given the right to review the arrangement from time to time and terminate the agreement for basically no good reason, then Disney's ownership *might* become much more important.
I say *might* because assuming Marvel still has the same top staff in place that it did prior to the merger, the long-time comics guys might not be too keen on Disney — with no real knowledge or appreciation of what they do — trying to tell them how to handle their own contracts. Basically, it might not be as simple as Bob Iger snatching back Spider-Man with a wicked laugh, if doing so would pi$$ off people with their own egos like Stan Lee or Joe Quesada (is he still running the show over at Marvel? He was back when I read comics).
Basically I'm still waiting to see what Disney "owning" Marvel really MEANS...whether the agreement stipulated that Disney would cash the checks and keep its nose (and lawyers) out of Marvel's well-established comics and licensing business, or whether the marriage will allow for Disney to take a more active role in Marvel's internal decisions.
So many questions about this arrangement, and I would love to have more details.
