Daniel Day Lewis played Lincoln as a posh Brit. It was all wrong. He hadn't the first notion of how to get him right.

Cumberbatch is super-British. He couldn't ever convincingly play someone who wasn't British.

Some actors can fit into another nationality enough, but some actors are way too stuck to their nationality and can't do it.

Cate Blanchett managed English well enough in the Elizabeth films, but she was a dead loss playing Irish in Veronica Guerin.
