At the time I had no idea who he was

I went to a showing of the first X-Men movie in one of the first theaters to have 3D sound (or something to do with sound, I don't remember) and dressed up as Rogue. NO ONE ELSE dressed up. I got stares and felt really, really stupid. He tapped me on the shoulder and said, "Wow, you're really dedicated aren't you?" At the time I had no idea who he was - he wasn't exactly dressed as Wolverine and he was pretty unknown - so I told him to piss off. He laughed and walked away. Now that I know... that was a really cool way for him to handle the situation.
