I find I differ from actor to actor. Like - I have no desire to see James Marsters as anything other than Spike, but I search around endlessly for more stuff with Kavan Smith. I watch everything Micheal Biehn does, but don't really care to see Adam Baldwin as anyone other than Jayne (although I loved him as Marcus Hamilton).

Mostly, it's weird to me to see the actors out of the fandom I find them in - and I don't always enjoy the performaces.

Thanks for answering, I'm always curious about how other folk see fandoms and actors.
