It’s come out today that it seems both Stewart and McKellen, who were previously reported as being in Days of Future Past, actually know nothing about it. The report comes from Entertainment Weekly but SuperHeroHype has all the details for both stories.
While I find McKellen’s thoughts credible, i.e., there was talk about him coming back, he says he’d do it, Singer assumed that still stood when he made the announcement.
But Stewart? Back in September there was an article on CinemaBlend where Stewart teases that he’ll be ‘reprising’ and then gets cut off before he says what role but it was in conjunction to a discussion involving the X-Men. Sounds to me like Stewart was at least in the same boat as McKellen, if not a lot more sure about a possible role in the film.
Could Stewart be playing it off? I can’t see why. Unlike, say, Marion Cotillard hiding the fact she’s Talia (which no one believed she was playing anyone other than her), there is a legitimate attempt to secure a plot point. There is nothing like that here. The only reason might be is if Stewart is trying not to sound either too excited, too needy, or too smug.
Whatever the reasons, I’m sure we’ll be seeing both men return to DOFP and it will be confirmed in the next few months.
