"I haven't done that cameo yet. It's almost scary because they just give me a date. They'll say, ‘Stan, come over next Thursday for your cameo,' but they don't tell me what it is. So, I show up and they say, ‘Go to wardrobe.' In wardrobe, they say, ‘We want to get you a white shirt and a green sweater and a black zippered jacket,' and I'll say, ‘Don't bother, I'm wearing one.' And then, they say, ‘But, you can't wear yours!,' and they look around and get me the exact same thing, but I'm not allowed to wear my own. And I still don't know what my role will be. I go on the set and one minute before we're gonna shoot, the director says, ‘Okay, Stan, this is what I want you to do.' So, I don't know what is expected of me, until I get there, but of course, I do it magnificently." -- Stan Lee, on being in Iron Man 3 .
