Why him? He’s got a definite Holms-ian look about him, and he’s got effects experience thanks to his work on Hitchhikers.

He doesn’t have a load of dramatic work under his belt, but this could be just the project to let him show some range. Plus, he’s still not exactly a huge star so Guillermo del Toro could secure his services for less than, say Daniel Radcliffe.

Why not him? Like we said, he hasn’t exactly proved himself as a dramatic actor, and he might not have made del Toro’s radar.

Chances are he’ll stay more in the realms of fan speculation – but stranger things have happened…
