A bunch of celebrities snuck undetected through Comic-Con in costumes (except for Jack Black, whose gut gave him away).

A lot of people talk about how Comic-Con gets more Hollywood every year, but they usually (and accurately) blame this on studios trying to take advantage of built-in audiences for nerdy franchises. What they don't talk about is the huge appeal this event must have for celebrities: a giant party where famous people can gain the power to act like a normal person by dressing up as a superhero. This year, Maisie Williams (aka Arya Stark from Game of Thrones), Daniel Radcliffe, Adam Savage (Mythbusters), and director Peter Jackson all managed to sneak around incognito at the fan event, and seemed to have had a great time. Jack Black, on the other hand...well, you'll see.
Mr. Harry Potter dressed up as another nerdy, bespectacled teen with dead parents and extraordinary powers and had a great time hanging out with the Muggles, even adopting an American accent to blend in.
Maisie Williams, who plays yet another bright kid with dead parents and possible powers (the other Starks seem chock-full of wolf magic... who knows?), also donned a Spider-Man mask so she could walk among the commoners. Slipping undetected through crowds is something Arya should be practicing anyway, as is being Anonymous.
