Can we talk for a minute about the RDJ/Marvel dispute? There are rumors flying around that RDJ might not return to reprise his role as Iron Man in the next installment of the film due to contract differences. Really? Is there any debate here? Can anyone else step into RDJ's shoes? It's not likely. 

But it is likely that Marvel (now owned by Disney) will take the Iron Man franchise as far as possible. Disney reps have been quoted as stating that the company is seeking to push Iron Man to Harry Potter proportions. In short: Disney isn't going to stop producing Iron Man films with or without RDJ. 

It's amazing to think that Disney purchased Marvel for $4 billion, and the Iron Man franchise alone has already grossed $3 billion including 'The Avengers' - which might not include any of the former cast if Disney keeps haggling over contracts (we wrote about this yesterday here). 

Analysts estimate that Disney could lose around 9% of its total earnings if RDJ walks away. That’s a lot of money when you’re talking billions. Does Disney have any real negotiating power here?

Here's a Marvel/Disney wake up call: Iron Man cannot exist without RDJ! RDJ is Tony Stark. The part was practically made for him. 

Has Marvel lost its marbles? Maybe; or, maybe Marvel is willing to take the risk. Just look at the number of James Bonds we’ve gone through in the past. Is RDJ replaceable? 

Comments? Thoughts? Can you really see someone else playing the part of Tony Stark? Heck, can you see someone else stepping into Pepper Pott's shoes (heels)?
