A Thought
I am watching F&Gs now, and I know Martin from Adventureland (awesome movie), Knocked Up (meh), and NTSF:SD:SUV, and I agree with all the posts that he is a fantastic and hilarious actor and definitely deserves bigger roles.
However, just a thought, maybe he doesn't want a lead. Just saying. I know myself am more comfortable 'behind the scenes' than being in a spotlight. Maybe he is the same way.
I don't know.
