DM: Me. I'd have to be able to sit back and watch this group kick it.
PLAYERS
Fighter: Kurt Russell (an aging warrior, who has to rely on all the tricks)
Sorcerer: Liv Tyler (she even looks the part!)
Rogue: Mathew Broderick (he was the perfect rogue in Ladyhawk, i couldn't less what anyone else thinks!!)
Wizard: Jeremy Irons (i am convinced he can do a Great Wizard, as opposed to the crap he did in the D&D movie. I blame script and director for that nonsense)
Bard: Dave Chapelle (the comedian. Dude has crazy range for characters, voices, and charisma)
Ranger: Harrison Ford. you know it.
I think that dynamic would be cool.
Harrison and Jeremy would be the players who took care of the specifics and always stay on course.
Kurt would be a fighter starting to break down and looking for that big score so he can retire.
Matthew would hide behind everyone (including Liv) and plan on how to steal the fighter's big score.
Liv would be the powerful and unearthly sorceress coming to terms with her abilities.
Dave would sit back and laugh at the rest of them!
Although i could see him doing the narration for the adventures. That would be cool.
