Oh, please, this one should be obvious.
Yep, I do think he's hot, but it's more his voice and how he becomes Sherlock that has won me over completely. Yeah, okay, I probably have a pretty heavy voice kink going here (Ben, Alan Rickman, Sean Connery, Hiro) but I just love accents and good voices. Hugh can get me on a good day, as can Stephen Fry. *giggles* I should probably add the trolls to the list, one for his voice and one for his accent. *sighs*
Anyway, back to Ben. If you want to know more about what he's done, or what he's going to be doing, there's a link to imdb.
