Guardians of the Galaxy director James Gunn recently announced that he would return to direct the third part of Marvel's space adventure series. Now Gunn has revealed that there could be a fourth part, but it would have to feature an entirely new team.

　　Speaking to the Toronto Sun to promote Guardians of the Galaxy Vol. 2, Gunn confirmed that the current narrative will end with the third movie. "I think the first three movies tell a single story and that story is pretty simple," he said. "I think that there could be a Guardians Vol. 4, but it would not be the same. It would not be the same group. Basically, the story of this group ends with Vol. 3."

　　The line-up of Guardians that feature in the movies have only existed in Marvel comic books since 2008. Prior to that, the team was entirely different. They first appeared in 1969, and included such characters as Major Vance Astro, Martinex T'Naga, and Captain Charlie-27.

　　There are two characters that overlap with the original comics and the movies--Yondu Udonta, played by Michael Rooker onscreen, and Starhawk, who is portrayed by Sylvester Stallone in Vol. 2.

　　Earlier this month, Gunn explained that he wanted to ensure that Vol. 3 ended the trilogy properly. "There is a history in Hollywood of haphazard endings to trilogies, and I didn't want to become a part of that dishonorable tradition of pretending the third one doesn't exist," he said. "My love for [the characters] goes deeper than you guys can possibly imagine. I feel they have more adventures to go on and things to learn about themselves and the wonderful and sometimes terrifying universe we all inhabit.

　　"And like in both Vol. 1 and Vol. 2, we will work on creating the story that goes beyond what you expect."

　　Guardians of the Galaxy Vol. 2 hits theaters on May 5--you can check out a trailer here. In addition, Telltale has now released the first episode of its adventure game series--click here to read GameSpot's review.
