In a video interview published on Yahoo! director of "Guardians" James Gunn said that he knew how to combine the two superhero teams together.

Actors from Guardians of the Galaxy also confirmed that the film was made with the expectation of continuation.

Vin Diesel who voiced humanoid Groot, suggested that the audience wants to see something like this.

Lead Actor Chris Pratt added that "it is very difficult, but Marvel knows its stuff" and "if they connect the two worlds, it opens the door to the third one.."

Recall you, that most of the characters of Marvel comics are living in the same fictional universe - "Earth-616". So, the heroes always can cross and act together in a new film!
