Comic-Con kicked off this week in San Diego, much to the delight of fanatical fans and zany zealots the world over. And, while some may go to catch a glimpse at the first trailer for a highly anticipated film – We're looking at you Interstellar! – see panels featuring the casts of their favorite television shows, from Game of Thrones to Teen Wolf, or just be able to say they saw Megan Fox in the flesh, the real action is in and around the venue, as the most die-hard devotees show off some amazing costumes.

Also showing off some amazing costumes this year? A-list directors Peter Jackson, who showed up dressed as a Jester, and Robert Rodriguez, who kind of phoned it in with a creepy mask. Both were on hand to promote their new films, The Hobbit: The Battle of the Five Armies for Peter, and *Sin City: A Dame to Kill For" for Robert.

Less excited about wearing costumes in public, ironically, were the actors, who all came and went in their finest dresses and suits. All that is except Daniel Radcliffe, who decided to roam the halls incognito in a Spider-Man costume.

So take a look in the gallery above at all the amazing costumes and amazing actors who made their way to Comic-Con this week.
