Do we have to have Q be an oldster? I mean, Desmond Lewellyn wasn't all that old when he began the role in the 60's, was he?
If Simon Pegg weren't already playing Scotty, he'd be good.. He can do dark and comic at the same time..
Colin Firth would be great at Q.. But of course, I don't think there's a chance in hell that he'd do the role now...
I'd like to see Colin Firth as M some day, I think he'd be great.
As for Q, Pegg's too geeky (and I know Q should be geeky but maybe not that geeky!)
