John C. Reilly's Guardians Of The Galaxy Clip From The Late Show With David Letterman

John C. Reilly, who play Corpsman Dey of the Nova Corps in Marvel's Guardians of the Galaxy, was a guest on last night's episode of The Late Show with David Letterman.

On the show, Reilly introduced a new clip from Guardians of the Galaxy. Somehow his character looks a little different than what we've seen previously. See if you can spot the difference in the clip below.

In Guardians of the Galaxy, in the far reaches of space, an American pilot named Peter Quill finds himself the object of a manhunt after stealing an orb coveted by the villainous Ronan.

Guardians of the Galaxy opens in theaters August 1.
