I'll say one thing for the casting directors over at Marvel, Inc, and that thing is this: they know how to cast their movies. Generally it's the villain side of the equation that gets us all excited -- probably because villains are more interesting than heroes and character actors are more compelling than movie stars -- but the latest word regarding my all-time favorite Marvel character has me, well, pretty psyched.

Mark Ruffalo's "breakout" performance was a damn fine one in You Can Count On Me, and fest-heads / indie fans have long realized that Ruffalo is a rather versatile performer. The guy can do vulnerable, tough, frustrated, sweet, funny, angry, etc. with no trouble at all. Even casual fans who noticed Ruffalo in films like Zodiac, Shutter Island, and Blindness were quick to point out how quietly memorable his work was. And while I enjoyed Eric Bana's inscrutible Banner in Hulk and Edward Norton's angry loner in The Incredible Hulk, I'm also rather impressed with Marvel's third casting choice. Guys dig Ruffalo's wise-ass straight-shooter approach, the ladies seem to like his manliness ... all in all, a fine choice.

Mr. Ruffalo will be joining Chris Evans (Captain America), Robert Downey Jr. (Iron Man), Chris Hemsworth (Thor), Scarlett Johansson (Black Widow), Samuel L. Jackson (Nick Fury), Jeremy Renner as Hawkeye and Don Cheadle as War Machine. It will be up to screenwriter Zak Penn and director Joss Whedon to bring this massive crew together -- and personally I cannot wait to see what this flick looks like.

So on this lazy day of flipping through all the colorful Comic-Con coverage, my question is two-fold: A) What are your favorite Ruffalo performances, and B) What are your thoughts on him joining the Marvel team as everyone's favorite green beast?
