Find out what powers, the X-Men first class cast member would take, if they could choose...

Michael (Magneto)

"I think the power to speak different languages. Is that a superpower? A tail would be kind of cool. You can balance and stuff with a tail. Be like a monkey. Or just for climbing, you know. Flying's pretty amazing, but you could fly with a tail… From tree to tree, like spider monkeys. Tail Man. Tail-linguist. Flying's the obvious one - it's like that thing of what animal you'd be if you could be any animal. It would be a bird, because flight is the one thing we can't do."

James McAvoy (Professor X)

"Erik's is such a good power, but at the same time I'm not that impressed with a man that can bend metal. It doesn't speak to me of drama. I'd love, love, love anything that was to do with flying. There's not much else you can wish for in life if you can pop down to the shops and not get stopped by the traffic. And I'd quite like to be able to heal people as well, like Elixir. We nearly had Elixir in this film, but ultimately we chose not to. I think it made everything quite hard to have real drama and sense of impending fatality if somebody could just heal people."

Rose Byrne (Moira MacTaggart)

"I'd like a combination. I'd like Charles's power to read and to block people's minds, but then I'd also love Angel Salvadore's power to acid vomit! I think that'd be useful. You're saying to the AD, "Where's my cup of tea?" Boom! Your reputation might be a bit ruined. You might burn a few bridges. Literally. Maybe just the threat of it – just a side spew so they could see what you've got... But yeah, I think a combination of a few of them would be really cool."

Jason Flemyng (Azazel)

"It would be Maestro – which means I can charge up anyone's credit card with the power of my mind. Or Oystro, for the tube. Or Alphabetico, which means it could be books or DVDs or music libraries, and I can just alphabetize them like that. Oystro – the lamest X-Men of all time. I just love the idea of lame superpowers. People can do amazing things like teleport and stuff, but with something like this it's still a power, it's just rubbish."

Nicholas Hoult (Beast)

"The one I have in the film's pretty cool. Even just to be able to have an opposable big toe and to be able to do things with your feet would be great. But this is a really difficult question. Obviously being invisible would be great. Flying would be great. But there are better ones, probably, than that. I'd like to be able to control people's destinies... That kind of sounds like I want to be God, doesn't it? I want to be God! There we go. I just spit that out and realised in hindsight that was a ridiculous thing to say! I;d quite like morphing – Mystique;s one – actually. That;s quite cool."

Jennifer Lawrence (Mystique)

Don't I have to say shape shifting? I would love to be able to run up stairs without falling, but I don't think that's a superhero power. Every time I run up stairs I fall, it's the weirdest thing ever. Basic human balance. Well. Flying would be awesome. But it has to be cooler than flying... Well, if I could fly it would solve my running up the stairs and tripping problem, because I could just fly up the stairs... So I'm sticking with that. And sharpening pencils with my eyes."

Caleb Landry Jones (Banshee)

"I wonder how many people have said teleportation... That's probably the best, I think. I'd be rich; I'd have travelled the world, possibly space. I could do all sorts of things with it."

Lucas Till (Havok)

"It's a tossup. I think you would want something like Shaw's power, where he can absorb kinetic energy and throw it back at something. That's all-powerful. But you also want a little style with it, like Magneto. It's not just all-powerful - he can bend metal and that's it - but there's a lot of things you can manipulate with that. I've always loved Magneto's power."

Edi Gathegi (Darwin)

"I'll tell you a story – I was an 'X-Men' fan growing up. I woke up every Saturday morning and I was glued to the TV when the 'X-Men' cartoon was on. And when the movie came out I loved it. It was the best superhero reimagining that I’d ever seen. I loved the 'X-Men' series. But Wolverine was the guy I loved when I was a kid. For some reason – the adamantium, the swagger, it was all about Wolverine. My character's relatively new – he was created maybe five years ago – and if my character were around when I was a kid, he'd definitely be my favourite character. I tell you what the powers are and you go, 'Wait a minute, that's awesome.' He wasn't around when I was a kid, but if he were it'd be all about Darwin."
