During Marvel's Comic-Con presentation in Hall H this summer, the studio unveiled the first trailer for Guardians of the Galaxy 2. While the big reveal from that footage was Kurt Russell as Ego the Living Planet, father of Star-Lord, there were plenty of other interesting details as well. Yondu (Michael Rooker) seems to be working together with Peter Quill, even after he double-crossed him at the end of the first movie. Sean Gunn, the brother of director James Gunn and the actor who portrays the Ravager Kraglin, offered some intriguing insight about how this sequel opens in a recent interview.

Shortly after the Comic-Con presentation, James Gunn shared photos of all the Ravagers, including the new leader Taserface (Chris Sullivan) in a lengthy social media post. The filmmaker hinted that Yondu has joined forces with Star-Lord and the Guardians, after the rest of the Ravagers weren't too thrilled that Yondu didn't retaliate against Star-Lord, when he double-crosed them, after he swapped out the Infinity Stone with a troll doll at the end of the first movie. ComicBook.com spoke with Sean Gunn at the Heroes and Villains convention in Atlanta, where he explained the opening moments of this superhero sequel.

"When the movie starts, it's only a couple of months after the first movie. The Ravagers have not gone hard after Peter Quill after he double crossed them with the Infinity Stone. There's a little rumbling amongst the Ravagers, like, 'Where does Yondu's allegiance lie here? Is he going soft on Quill?' So, the Ravagers have to make a decision of what they're gonna do about Yondu and I think Kraglin is a key part of that, but that's all I can say."

Aside from his portrayal of Kraglin, Sean Gunn has another important job on the Guardians 2 set, serving as the motion-capture reference for Rocket Raccoon, while Bradley Cooper returns to provide Rocket's voice. Sean Gunn revealed that Rocket has plenty to do in this superhero sequel, and that he starts questioning his place among this team. Here's what Sean Gunn had to say about what happens with Rocket Raccoon in Guardians 2.

"Oh yeah! Rocket has a lot of great stuff to do in this movie. There are a few relationships that are central to the theme of the movie and that really go towards keeping a family... and Rocket has the same sort of crisis of faith about whether or not he belongs in this family or not. I'm really grateful to work on the movie in that capacity. I'm a team member when it comes to Rocket. It's much different from other acting jobs that I have, but it's still really cool and special."

Before the first Guardians of the Galaxy hit theaters, some thought that this adaptation featuring some of Marvel's more obscure comic book characters, might be Marvel Studios' first box office bomb. That theory couldn't have been farther from the truth, with the movie earning $333.1 million domestically and $773.3 million worldwide from a $170 million budget. When asked how this sequel will be different from the original movie, Sean Gunn had this to say.

"I do think that it tries to touch some of the same notes that worked in the first movie. It's a tentpole movie, meaning it's literally for everyone. It's not just a kids' movie disguised as an adult movie or vice versa. I really think it's for all ages. I really do think it really has a heart but it's a comedy, as well. I've heard my brother [director James Gunn] say that the first movie was sort of about creating a family the second movie is more about being a family and the struggle of maintaining that. I think that's spot on and I hope that's what resonates with people. I can't wait to share it with an audience"
