Today at 1 p.m. ET, "Guardians of the Galaxy" director James Gunn and a few cast members held a Q&A on Facebook.

Gunn, Chris Pratt, Dave Bautista, Karen Gillan, Marvel Studios President Kevin Feige and Vin Diesel took turns answering questions about the movie from fans.

Gunn answered quite a few questions on just about everything. When asked if he would direct a sequel to "Guardians," he said, "I believe I am contractually obliged to do that whether I want to or not. But, of course, I'd love it. I love these guys so much -- the guys at Marvel and the cast. They've become very close friends."

Gunn also revealed some influences for the movie, such as Magritte's Empire of Light paintings, "epic" science fiction films and westerns.

Karen Gillan joked about getting into character. She was asked what she thought when she saw herself in the mirror after the five-hour makeup process. Gillan said, "What an improvement!"

She also said that "Doctor Who" prepared her to act on spaceships.

Vin Diesel explained that the most challenging thing about getting into character was working so soon after the death of Paul Walker. It was the first time he worked, which was tough but therapeutic.

"There was an innocence about the character that was just refreshing -- and it may have been more challenging under other circumstances, but at that time, it was very therapeutic," Vin Diesel said.

And if you're wondering, Vin Diesel said "I am Groot" about a thousand times, or at least it felt that way. He said the phrase was used to mean so many different things, and that it was interesting to see what he could do with so little.

Dave Bautista explained that wrestling didn't help him too much with his fight scenes. He said that he just trusted the stuntmen and took their advice.

Bautista was also asked about who would win in a wrestling match between him and Chris Pratt, and he said that Pratt used to be an amateur wrestler. Pratt even tried to set up a match between the two.

Chris Pratt admitted to not reading any comic books to prepare for his role, but Gillan said she read the Infinity Gauntlet.

But let's be honest, the best part of the chat was the new trailer that was released.
