While I love to poke fun at the sheer ridiculousness of San Diego Comic Con, there are some pretty cool things about it. One of the things I’ve always enjoyed reading about is celebrities getting the chance to walk through the crowds completely incognito, thanks to a mask or costume. So many people are dressed up or disguised in some way, that they can blend right in at an event where they would normally be mobbed. Some of them will later reveal themselves, some make a game of it as they’re walking the Con floor, and some probably keep it to themselves entirely and we’re never the wiser. Here’s a few celebrities who have used cosplaying to their advantage this year:

Maisie Williams, Game of Thrones
Everyone’s favorite tiny swordswoman just threw on a mask (or two) to enjoy the Con floor this year, but it looks like it worked for her!

Daniel Radcliffe, Horns
Daniel was there to promote the upcoming movie Horns based on Joe Hill’s novel and also got into character as everyone’s favorite web-slinger. In another interview, he mentioned that he wore a backpack and used an American accent just to complete the deception.

Jack Black, Goosebumps
Jack Black tried to wander the halls an an anonymous Storm Trooper, but was caught by TMZ. He seems confused as to why he was recognized, but since it looks like he’s wearing his official con pass, that might be a hint. (Warning, video is extremely irritating and I’m only posting it due to a lack of alternative sources.)

Adam Savage, Mythbusters
This has become something of a yearly tradition for Savage and he seems to get most into the spirit of cosplaying, even risking heat exhaustion for the sake of his costume.

Peter Jackson, The Hobbit
Peter Jackson dressed up as an evil jester, and even took pictures with fans while they had no idea who he was. He posted the reveal on his Facebook page.
