Before you get your hopes up about an X-Men or Spider-Man and Avengers crossover - don't.
It's unlikely. The movie rights to the X-Men and Spider-Man properties aren't owned by Marvel. What seems more likely is a crossover with Guardians of the Galaxy. It makes sense that Marvel would tell Vin Diesel about possible plans in this regard if he's to be working on Guardians of the Galaxy.
When I met with Marvel it wasn't for anything immediate, it was to talk about a film that would be introduced in the Phase 3 part of Marvel, not for a few years. You wouldn’t be able to see it for a few years. In my mind, Marvel were doing it right, they were enrolling me at the ground level which is the best way to enroll me.
I had heard people over the last year, people saying on the social media page saying “What’s up Vin? Why aren’t you going to Marvel? Why aren’t you doing anything with Marvel? It would be a crime of cinematic history for you not to be in [Marvel movies]”
So I was thinking “This Marvel thing is really becoming really important for these people. What can I do? What should I think about?”
I get the call, I go down to Marvel. A great meeting. It was even talking about something so big I can’t even talk about because it’s like the merging of brands in a way, which I won’t get into. That was something way, way, way, way, way down the road.
Regarding Comic Con:
We had agreed not to say anything about the specifics of the meeting. So, now I’ve got the fans who I love more than I love the industry, than I love everybody… I was thinking “I’ve got to be real with them, I’ve got to tell them something” and yet I want to be respectful of people’s process and if people like to do a slow reveal, you know?
Quite frankly, it would have been too much to say and it might have been anticlimactic to say “We’re working on something for 2016” and so I just said “You’re going to hear some really big news” and I left at the end of that and it went crazy.
The next Monday, Marvel talks to me and says “We’re going to send something over in two weeks. We want to focus on the 2016 but we also want to, if possible, answer this growing request for something now.” I don’t have six months to play a character in the immediate future, it’s all booked… there was no way I was going to be able to deliver… after Comic-Con, we were at a stalemate…
