Next year, the summer movie season kicks off with Marvel's highly-anticipated Phase 3 sequel Guardians of the Galaxy 2, which brings back all of your favorite intergalactic misfits to theaters on May 5, 2017. Aside from the Guardians of the Galaxy themselves, one of the other returning characters is Karen Gillan's Nebula, the sister of Zoe Saldana's Gamora, and it seems that director James Gunn may be eyeing a possible spin-off. Nothing official is in the works, but this is something James Gunn has considered before, it seems.

Yesterday, James Gunn responded to a fan on Twitter, who said he thinks Marvel should make a Nebula movie and that she is his favorite character. The director offered a surprising response, teasing that he's considered a Nebula movie ever since he signed on to direct the first Guardians of the Galaxy. Here's what James Gunn had to say on Twitter below.

"I have a few favorites myself, but I agree that Nebula should lead her own film - it's something I've thought about from the beginning."

In the first Guardians of the Galaxy, we saw quite the contentious relationship between Nebula and her sister Gamora, but a report from earlier this year revealed that Nebula was actually joining the Guardians of the Galaxy team, along with Michael Rooker's Yondu. While we still don't have any official plot details yet, James Gunn revealed in a September interview that this sequel will explore the relationship between Gamora and Nebula.

"The first movie was really about becoming a family. This movie is about being a family. And what's harder, becoming a family or being a family? I think it's being a family. That's where you really have to deal with each other. And that's what this movie is about. And their sisters. They are family, whether they like it or not. And they also want to kill each other, so it adds a new twist to being a sister."

These details come just a few days after James Gunn offered a heartfelt statement in honor of International Day of the Girl, where he revealed that this sequel passes the Bechdel Test, which means the movie has at least two female characters talking to each other about something other than a man. The first trailer debuted during Marvel's Comic-Con presentation, but that footage hasn't been released to the general public quite yet, and we don't know when the first footage will be made available to all. Take a look at James Gunn's tweets below, as we continue the countdown to Guardians of the Galaxy Vol. 2, in theaters May 5, 2017.
