re: who are the top 5 biggest pricks/coolest bros in hollywood

You can tell who is a nice guy by who gets a ton of small roles because people want to work with him. It shows that the person is not a problem, and gets their work done, a good sign of a decent human being, or at least not a diva. Guys like John C Reilly, James Spader, or Steve Buscemi show up in so many different kinds of movies you just know they are easy to work with. And for some reason, guys who play a lot of villains tend to be nice guys. It's the Alan Rickman Effect.

Also, my sister in law is sort of neighbors with Kurt Russell (his massive ranch is outside of her town, but the Russell/Hawn family comes into town a lot), and she reports Kurt is just as cool as you imagine him to be. Which, for me personally, is pretty damn cool.
