I could not remember this guy from the movie. (Saw it 3 times) Then I went to IMDb.com. He is an uncredited extra. Which means he had no lines and was in crowd scenes. So the comic-con is having extras from the film come in and sign autographs? The first clue is the only picture you can find of him is a blurry shot from a distance. Kind of like a sighting of Bigfoot. Were there no actors available that had speaking parts in the movie? Only extras with no lines that I dare you to try and spot in the movie. So, why interview an extra and why have him at the convention like he was a real actor in the movie? Seems kind of shady.
