So, how old does everyone think Hoff actually IS? Remember, Patrick Stewart is not a young man. And from the fluff I'd assumed that Hoff was in his early to mid 20's, as his older brother Ryle was at Oxford.
Personally I'd add him, but as Ramos. He's got the gravitas to pull it off.
And then we can throw in James McAvoy in as Hoff, and go to town
Re: Lucius: I'd actually wanted Hugh Laurie to play him because of reasons (see below), but damned if Cumberbatch wouldn't be perfect for the role. No idea what other master he could be....
