Rumor: We Might Know Who Nathan Fillion Is Playing In Guardians of the Galaxy

Potential spoilers below!

Over the weekend, we all found out that our favorite hammer-themed superhero (sorry, Thor) would have a “fun” featured cameo in the upcoming Guardians of the Galaxy movie. Now several media outlets are running with rumors that they know exactly who he’ll be playing: Cosmo, the talking Russian cosmonaut dog who sometimes uses his psychic powers to help out the Guardians and make fun of Rocket Raccoon. Obviously we don’t have to tell you that this needs to be a real thing. Don’t Bryan Cranston-Lex Luthor us again, Internet!
