Man, I tried running through the list in my head, and most of them are dead. I'm getting fucking old.
Ed Norton is still alive. Steve Martin. Patrick Stewart. Ian Mckellan.
Fuck, that's about it. And there's no actresses alive on my list. Weeelll, maybe Susan Sarandon, but isn't she semi officially retired? I think she is anyway. I guess you could count Helen Mirren, but I wouldn't go see a movie just because she's in it. I would, however, watch a movie that she's in, even if it isn't a movie I would otherwise be interested in.
If I use that criteria, you can add Ryan Reynolds to the list as well. I'll give his stuff a watch just to see how it is, though I won't go out and hit the theater just because he's in something
