7. Jack O'Connell
The newly crowned BAFTA Rising Star has had a terrifically big last couple of years, going from disarming TV talent in Skins to working with Hollywood Royalty in Unbroken with Angelina Jolie, and the next few are likely to be even bigger (unless the BAFTA curse takes him down). Right now, his slate is relatively clean, but expect that to change fairly rapidly. Pros It would be a radical departure from what's been before: while Andrew Garfield was very much considered an edgier choice than Tobey Maguire, he's basically PG-13 era to O'Connell's Attitude Era in wrestling terms. He's played villains and anti-heroes predominantly (aside from Unbroken and the exceptional '71), and there's far more of a swagger about him. Cons Again, he's a Brit, so there might be grumbles. And, in very much the opposite spirit to Logan Lerman, he's already built a reputation as having a bit of a bad boy on-screen persona, and that probably doesn't fit all that well with being the poster boy for Stark's superhero registration movement.
