While director Bryan Singer toils away in post-production on X-Men: Days of Future Past, star James McAvoy recently teased the massive scope of this sequel.

"There's an army of brilliant actors in that film. Bryan Singer is back at the helm. Potentially it's going to be the biggest, most epic X-Men they've ever had. I think it's the second biggest production Fox have ever embarked upon, behind Avatar. So they're definitely going for it. Bryan is very protective of the series. He did create it. He did help form that environment that allowed subsequent superhero movies to exist and thrive like they have done for the last however many years. Not to say that there weren't other superhero movies out at the time, but of that ilk, where it was OK to take it really seriously. He does take it really seriously. There's a kind or reverence about it, which I like. You want people to take it seriously. That's what he brings to it I think. And a safe pair of hands - you know you're in good hands."

The actor also talked about working with Patrick Stewart, who plays an older version of his Professor X character.

"His last day was my first day and that was it. Then we were done. But we did crossover and we do get a scene together. Getting to work with Hugh (Jackman) - who I christened Hugo Boss - was great. What he's like on camera when he's getting interviewed and you think he's the nicest man in show business - he is. He's amazing. The guy's got grace coming out of every single pore. If we could all be a bit more like Hugh it would be a very happy planet."

In 2011's X-Men: First Class, a majority of the actor's screen time was with Michael Fassbender's Magneto. However, James McAvoy said that isn't the case this time around.

"Getting to work with Michael (Fassbender) again was great. I spent a hell of a lot of time with Nick [Nicholas Hoult]. Weirdly the people that I spent the most time with acting-wise was not Michael this time, it was Hugh and Nick. And whilst I bemoaned the loss of my buddy Michael, it was more than made up for by the fact that Hugh and Nick are such amazing people."
