This weekend one of the big trending things on the internet springs from a rumor that Nathan Fillion would show up as Richard Rider (a.k.a. Nova) in Guardians of the Galaxy.
Yesterday James Gunn debunked that rumor saying that Fillion is not going to be Nova in the movie, however someone asked him a follow-up question and he did confirm that there is a cameo for him in the movie:

It’d be pretty awesome if Fillion provided the voice for Cosmo, the talking dog who’s in charge of security on Knowhere.
