It has long been rumored that actor Nathan Fillion would cameo in Marvel’s upcoming “Guardians of the Galaxy.” Latino Review reported that Fillion would portray Richard Rider a.k.a. the super hero Nova. Director James Gunn is denying these reports, but after constant badgering by fans, he has reluctantly admitted that his long time friend will be in the film.

The rumors of my pal @NathanFillion playing Nova in #guardiansofthegalaxy have been greatly (and entirely) exaggerated. Sorry, humans.

One fan pushed for the truth about the cameo, which made Gunn respond immediately.

@burnettski92: @NathanFillion Just what you’d say if you wanted to keep his appearance a surprise.” I would never & have never lied to fans

It appears Gunn wants to keep his truthful reputation intact. He finally caved and confirmed that Fillion will indeed be in the film, just not as Nova.

@STARS_TyranT: Are the rumours true that he has some part in the film?” @nathanfillion has a very small fun cameo he did as a favor to me.

Since Fillion will have a cameo in “Guardians of the Galaxy,” who or what will he play?
