Guardians of the Galaxy cast "Goonies" star Josh Brolin to play the villain Thanos as confirmed by the sources of Variety.

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 on saying that Thanos would probably seen more in the after credits of the movie.

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."

Meanwhile, Guardians of the Galaxy movie is just around the corner and Disney's boss Bob Iger is already excited about the future of the film and its characters.

ComicBookMovie.com reported that Chairperson Bob Iger was really optimistic about the future of Marvel during a conference call with Disney shareholders.

According to the publication, Iger even warned competitors that "Guardians Of The Galaxy" is set to help the studio sky rocket to a new level.

"This August 1st, we're looking forward to introducing the world to more fantastic Marvel storytelling," Iger stated, "with a great cast of new characters in 'Guardians of the Galaxy', which we screened last week and we believe it has strong franchise potential."

Disney's chairman added that the recent screening of the film was a rather huge success and it will certainly add to the studio's box office hit movies including "Captain America: The Winter Soldier" and "Thor: The Dark World."

"Guardians of The Galaxy" cast will definitely bring Marvel into an entirely new realm as it is focused on the different galaxies from space unlike previous Marvel superhero films.

"That's a whole other Marvel realm or universe in terms of where it takes place," Iger explained, "the characters that populate it and the stories that you can tell for those characters. So, I think, I'm not going to predict that we've got another Avengers on our hands, but that's certainly the goal."

Despite Iger's positive views, it is almost impossible for "Guardians of the Galaxy" movie to reach Avengers, Thor or Captain America's success in the box office but, it can in the future films judging by Marvel's Cinematic Universe.
