One more rumor to throw into the mix, from the same guy that said Garry Shandling would be Senator Stern, we now hear that Gary Oldman was spotted on set. One rumor, which I believe is just speculation, is that Oldman will be playing Howard Stark, Tony’s father. It was previously thought that Tim Robbins would be playing this role.
Update: Gary oldman’s manager, Douglas Urbanski, he posted the following at SHH:
“Mr. Oldman did not visit the set of Iron Man and there are currently no plans for him to appear in the film.”
