Guardians of the Galaxy post credits scene has allegedly leaked online and according to rumors it'll be all about "Thanos" and "Nova."

"Goonies" star Josh Brolin has been cast as the red-faced villain while Nathan Fillion is reportedly going to portray Richard Rider aka Nova.

Thanos previously appeared in the post-credits scene in "The Avengers." He is also expected to appear in both the upcoming "Avengers" sequels as the major villain.

"We're definitely tied to 'Avengers 3,'" director James Gunn recently revealed of the upcoming "Guardians of the Galaxy," which hits theaters Aug. 1.

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 post credits scene.

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."

On the other hand, with Fillion reportedly portraying Nova it is safe to assume that he will not be cast as Green Lantern in DC Comics upcoming movie adaptations.

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