Guardians of the Galaxy movie end credits revealed! Apparently, the post credits scene for Marvel's upcoming intergalactic superhero film is entirely dedicated to "Thanos" and "Nova."

Nathan Fillion is rumored to be portraying Richard Rider aka Nova in Marvel Cinematic Universe, while "Goonies" star Josh Brolin is already confirmed to take on the role of "Avengers Age Of Ultron" villain, Thanos.

However, Fillion and director James Gunn both denied the news of the "Nova" character and its appearance in GOTG movie.

"You won't see the Nova character in the film. You'll see the Nova Corps," says Gunn.

He further expressed his frustration in the rumors saying,  "Nathan Fillion is not Nova. There's so much bulls*** on the internet. I woke up - first it's 'Nathan's Nova!', then there are articles all over saying Nathan's Cosmo. It's like, 'What?!' Nathan's role is a very small cameo that I wanted to give to Nathan because I love working with him and I think it's lucky for me to have Nathan in all of my movies. At the same time I wanted to give him something where Nathan could have a larger role in the Marvel Universe if either Joss [Whedon] or I or whoever chose to do that in the future. Which I would love to do. I would love to give Nathan something he could really chew on, but it didn't work out on this movie for two reasons. Number one - because he was shooting Castle. And number two, because it just wasn't the right exact role for him."

On the other hand, Fillion himself clarified the news about also being "Cosmo" saying:

"With so much inaccurate 'news' about my involvement in GOTG, I'm actually losing faith in the internet. I'm not Cosmo," he posted on Twitter.

However, Gunn did not deny having Thanos in the Guardians of the Galaxy movie end credits scene in fact he even revealed that GOTG is connected to the upcoming Avengers movie, where Thanos is about to take on the main villain role.

In addition, director James Gunn confirms, "We're definitely tied to 'Avengers 3."

And, with the recent development, speculations began to rise about how small or big Thanos' role in James Gunn's film would be.

Moviepilot.com gave its two cents, saying that Thanos would probably be seen more in the Guardians of the Galaxy end credits scene rather than in the movie itself.

Bobby BoxingFanatic Borges said:

"The last we saw Thanos was at the ending of the Avengers film. Not even a 10 sec scene that shows him. Now my idea is I could envision Thanos getting a hold of a gem that might be included in Guardians of The Galaxy. I could see Thanos looking at Asgard as saying something like "Ah...Odins treasure room" and then cuts off. It would make sense since Guardians of the Galaxy already takes place in a cosmic setting. Reintroducing Thanos would keep us interested in Avengers 3. I wouldn't be shocked if some similarity of this scene may occur."

Going back to what director James Gunn claimed, Moviepilot also speculated that since Guardians and Avengers are allegedly connected, the after credits may be: "we could see Loki ruling Asgard [as we all took a hint at the end of "Thor: The Dark World"] and/or we can get the first official look at Ultron from Avengers: Age of Ultron."

Guardians of the Galaxy is scheduled to hit theaters on Aug. 1, 2014.
