That says a lot for Max
As for Heath, damn. Brokeback was, in my opinion, his best. I haven't seen all his movies, but if you can, you should see some of them:
A Knight's Tale: My absolute favorite after Brokeback, I love it. It was made before Brokeback, when he was still a "teen idol". But his acting, his presence, is just great. Rufus Sewell, another one of my favorites (Zen) is in it also.
10 Things I Hate About You is a great "teen movie", you should really watch it if you get the chance. He is dynamic.
Casanova: I saw this after Brokeback. He's amazing (I know I use that word a lot for him, but you have to see him)
Monster's Ball: I did not like the movie. I watched until his character was out of the script. Not an easy movie to watch, but he is amazing. I read that this is the role that got him the Brokeback part.
I never saw The Brothers Grimm, I'm Not There, Ned Kelly and some others. But I really think you would like the ones I listed, Knight's Tale is my favorite, he doesn't hide his accent and I love that.
