Earlier this month, we reported that the story treatment for Guardians of the Galaxy 2 is complete, with James Gunn now working on the actual script itself, as shooting is scheduled to begin in February 2016. Last night, the filmmaker took a break from writing to attend the Avengers: Age of Ultron premiere in Hollywood, where he revealed a few new details about the sequel. At the heart of last year's Guardians of the Galaxy was Star-Lord's (Chris Pratt) relationship with his mother before she passed away, while introducing the mystery of who his father really is. James Gunn confirmed that while the first movie is about mothers, the second is about fathers.

"There's a lot of stuff I'm excited about in the new movie. Listen, I'm still excited about Star-Lord's character and where he goes. At its heart, Guardians is a story about families, and if the first film was about him and his mother, this is a story about fathers. So it's exciting to go there."

The director confirmed last year that Guardians of the Galaxy 2 will reveal who exactly Star-Lord's father is, and that it won't be the same character from the Marvel comics, J'son. What's interesting is his use of "fathers" as a plural. Perhaps this means the sequel will further explore the issues characters like Gamora (Zoe Saldana) and Nebula (Karen Gillan) have with their father, the Mad Titan himself, Thanos (Josh Brolin). The filmmaker also says that he has known for a long time what the sequel's story will be, while teasing a third installment.

"I knew for a long time what the story of the second one was gonna be. And the third one!"

While no cast members have been confirmed yet, Guardians of the Galaxy 2 will surely bring back the Guardians themselves, Star-Lord (Chris Pratt), Drax the Destroyer (Dave Bautista), Gamora (Zoe Saldana), Rocket Raccoon (Bradley Cooper), Groot (Vin Diesel) and possibly Yondu (Michael Rooker) and Nebula. Do you have any theories as to who Star-Lord's father may be? Let us know what you think, and stay tuned for more on Guardians of the Galaxy 2.
