Several months ago Nathan Fillion who is close friends with Guardians of the Galaxy director James Gunn as well as The Avengers director Joss Whedon revealed he has a role in the upcoming space epic. Then last week we got word that Richard Rider maybe making a cameo in the film and Latino-Review simply speculated that Fillion might be Nova in this post-credit scene. This of course was quickly debunked by director James Gunn....
Now while its been revealed that longtime Guardians of the Galaxy talking dog Cosmo will be cameoing in the film it would be unknown if he would talk (Well telepathically) but it seems he will! According to Schmoes Know Fillion came in to provide the Russian voice for Cosmo in Guardians of the Galaxy
"According our very reliable source with intimate knowledge of this and the production has spoken exclusively to us about this and we here at Schmoes Know have our answer: Nathan Fillion will be voicing the part of Cosmo, the psychic Russian cosmonaut dog that has appeared in the Guardians of the Galaxy comics."
Guardians of the Galaxy hits this August
