Nathan Fillion: Everything You've Heard About The Guardians Of The Galaxy Cameo Is Wrong

We've been excited about the prospect of seeing Firefly star Nathan Fillion in Guardians of the Galaxy going back to April when the actor hinted at a small cameo in the Marvel Movie at the St. Louis Comic Con. We've spent the time since quietly speculating about and anticipating the part, and earlier this week it finally looked like we got a beat on who Fillion would be playing. It turns out, however, that it was just another one of the internet's famous spun falsehoods.

After speculation spread around a couple days ago that Nathan Fillion would be voicing Cosmo, a psychic Russian cosmonaut dog, in Guardians of the Galaxy, the actor took to his official Twitter account to shoot down the story:

So if he's not playing Cosmo, who could he be playing? When Fillion first teased his Guardians of the Galaxy cameo, he told the St. Louis Comic Con audience that his role would be a surprise and that fans would probably have to check the credits to find out exactly who he played. While Cosmo is actually a pretty good fit for this description - most people probably wouldn't recognize Fillion's voice, especially if he was affecting a Russian accent - I think the safe money now is on some kind of alien covered from head to toe in prosthetic makeup. We already know that the Marvel Studios films is going to be packed to the gills with all kinds of weird alien creatures coming in and out of frame, and Fillion could be playing any one of them. I guess we have to assume that he will have one line of dialogue, otherwise I'm not sure why writer/director James Gunn would have asked him to be in the movie.

Even if Fillion wasn't appearing in Guardians of the Galaxy - and thankfully he is - it's still hard not to marvel (pardon the pun) at the cast the space epic has put together. Leading the ensemble as the titular team is Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper and Vin Diesel, but they are surrounded by an absolutely outstanding pack of supporting actors, including Lee Pace, Michael Rooker, Karen Gillan, Djimon Hounsou, John C. Reilly, Glenn Close, Benicio Del Toro and Peter Serafinowicz. Even if the movie didn't look incredibly badass and funny we would still be interested in the movie from the cast alone.

The 10th film set to be released by Marvel Studios, Guardians of the Galaxy will be taking audiences into the deepest reaches of outerspace where they will follow the tale of Peter Quill, a rogue who trots around the universe stealing stuff while going by the name of Star-Lord. When he comes in possession of a mysterious orb, however, he suddenly finds himself with a target on his back some of the most dangerous beings in the universe aiming right at him. In order to both survive and save the galaxy, he must team up with four other misfits like himself - Gamora, Drax The Destroyer, Rocket Raccoon and Groot - and save the day.

Guardians of the Galaxy will be arriving in theaters August 1st.
