Howard to Play 'The Joker'

Howard played a clip from Saturday's GeekTime in which 'Iron Man 2' director Jon Favreau revealed that the name of Garry Shandling's 'Senator Stern' character was a shout-out to the show: "Of course!"

Howard said he would have played the character himself--but changed his mind, saying he would have preferred a larger role: "Quite frankly, I'd never take a cameo...I'm going for the Oscar."

Howard said he hoped to take over for Heath Ledger as 'The Joker' in the current Batman franchise: "I'm waiting for the sequel to 'The Dark Knight'...I just won't do anything."
