Daniel Radcliffe hit up Comic-Con 2014 to promote his new film, 'Horns,' but the 'Harry Potter' star was determined to have some fun away from the glare of the spotlight. Fortunately, the charming actor was in the right place for that, and he did it quite handily...by dressing up as Spider-Man. Where else can a full-grown man dress up as a superhero and not get a second glance? Point to Radcliffe.

Radcliffe shared his experience on last night's 'Jimmy Kimmel Live,' as well as a few special peeks at his very cool costume -- and just when you thought you couldn't love the guy more! Be sure to stick around for Radcliffe's mention of his favorite costume at Comic-Con. It's worth it just to hear him stick too incongruous words together and say them out loud.
