Although Stan Lee previously stated he wouldn't have a cameo in "Guardians of the Galaxy," it looks like he'll make an appearance after all. During Stan Lee's panel at C2E2 2014, Lee confirmed he has filmed a cameo appearance in Marvel's upcoming summer film.

"I already did! I cant tell you want it is --" Off stage, the associate who earlier stopped Lee from elaborating on the hologram was shaking his head. "Aw, now they'll get mad at me. I can tell you I don't understand what it was or why I did it. It was with a girl, a pretty girl. But you'll get a kick out of it. But if you understand it, write me a note an explain it to me!"

The earlier incident about the hologram may actually have something to do with his "Guardians" cameo, as Lee appeared without his signature mustache for the panel -- he had shaved it off for an on-camera role.

"Oh, you know what happened? Somebody decided they wanted to do a hologram --" Lee stopped, looking over to the side of the stage where one of his associates was shaking his head, "Oh. I can't talk about that! Well, I had to do something before the camera that called for me not wearing a mustache, so I shaved it off for this. I got home, and my wife said, 'Wow, you look better without the mustache.' And the guys at Pow! said, 'Oh, you look better without the mustache.' Well, I don't need a house to fall on me, so I want to keep it off. But now everyone says, 'Where the hell is the mustache?!' So I don't know what to do."
