It's hard to imagine anyone else other than Hugh Jackman (aka Huge Jacked Man) playing Wolverine in the X-Men films. The man grabbed hold of the role and absolutely ran with it, churning out some OK, to not-so-great, to bad, to an ultimately amazing film about everyone's favorite grumpy mutant.
And although the role absolutely belongs to Hugh, even if he admits he's "too tall" to play the muscular little harbinger of death, it wasn't always Jackman's role. That's right, Fox originally pegged Dougray Scott for the role.
If you're trying to remember who Scott is, he's the handsome Scotsman who played the main villain in Mission Impossible 2. Watch him dramatically grab this scarf from blowing away in the wind.
