Here’s a fun story! James Gunn, who directed the smash hit Guardians of the Galaxy for Marvel last year, walked around Comic-Con in a Joker mask a couple of years ago. Best of all? Disney (Marvel’s parent company) gave him the mask! Gunn told the story on Instagram today in a “throwback Thursday” post this week:

While in the middle of shooting Guardians the cast and I flew out to San Diego for a secret surprise panel at Comicon. The Disney folks asked us not to leave our rooms so we wouldn’t tip off the fans about the appearance – but there was no way I was going to stay in my room for a full day. Rooker and I asked for masks so we could go to the con incognito, so Disney brought each of us one. This is the one they brought me. A Joker mask. “Uh, you guys realize Joker’s not Marvel, right?” I said. “Um, well, I just kind of bought what was right there,” Disney person said. I didn’t care. I like Joker. So this is what I wore around SDCC for the day. It was uncomfortable as hell.
