It's nice to see that Magneto and Professor Xavier are such good friends. In real life, that is: Sitting with Michael Fassbender and James McAvoy for about four minutes is all you need to learn that the two are obviously close, with their effortless, enjoyable rapport. In fact, I didn't even have to ask much – these guys pretty much take it away from the moment we start rolling.
In the interview below, Michael and James (and I) talk about returning to their roles, existing in the same film as their "older" selves (played of course by Ian McKellen and Patrick Stewart) and the magic of Comic-Con. (You'll want to hear James' SDCC story.)
