Forbes talked to Stan Lee, who says he will be filming another cameo soon:
I’ve already done my Iron Man cameo. I think you’ll get a big kick out of it when you see it. They shot The Hulk I think in Toronto and other places and I wasn’t able to fly there. But they said by the end of this month or the beginning of next month, they’ll try to shoot a scene or so in Los Angeles so I can do a cameo, so I’m waiting expectantly.
I was the mailman in Fantastic Four. In the first Hulk I was walking out of a building with Lou Ferrigno. We were two security guards. In the new Hulk I hope I’ll do one if they shoot a couple scenes in L.A.
Iron Man hits theaters on May 2, and The Incredible Hulk on June 13.
