Personally not a huge fan of Dennis Quaid. Did you see him in GI Joe?
And he is pretty old to play Rendar.
I just don't think Quaid has much talent.
GI Joe is a TERRIBLE sample for Quaid. I really like him, but that movie as a whole was just embarrassing. He's not an A-List actor by any means. He is what he is and doesn't try to do more than he's capable of.
As for him as Dash Rendar, no. Absolutely not.
Just some interesting names (I haven't made a full decision on my opinion yet):
Michael C Hall
for the sake of the SHH Forums..... John Krasinski
