A new behind-the-scenes look at Guardians of the Galaxy Vol. 2 explores how the Guardians have become more of a family since the first film. A lot of exciting news has been coming out about Vol. 2 ahead of its May 5 release, including details on how the Guardians will fit into the world of their Marvel superhero counterparts in Avengers: Infinity War, and the announcement from writer-director James Gunn that's he's already started work on Guardians of the Galaxy Vol. 3.

In addition to cast and crew members telling stories about the past, present, and future of the Guardians, Marvel Studios has been releasing production featurettes highlighting some of the fun exploits on the film's set. The newest video keys in on family an important element at the center of Vol. 2.

With Sweet's sweet '70s hit "Fox on the Run" serving as the featurette's backdrop, the footage includes lots of goofing around on the set by cast members, as well as interviews with Dave Bautista and Pom Klementieff. Speaking of the film's family theme, Bautista says:

"To me, this is more of a relationship film, and your family doesn't always have to be blood. it can be chosen."

Also included in the video is an interview with Gunn, who says the "sequel is about getting to know the characters in a deeper way." He adds:

"The first movie was about becoming a family. This movie is about being a family."

The Guardians family nearly doubles in size in Vol. 2. Joining Star-Lord (Chris Pratt), Gamora (Zoe Saldana), Rocket (voice of Bradley Cooper), Drax (Bautista) and Baby Groot (Vin Diesel) are new Guardians Yondu (Michael Rooker), Nebula (Karen Gillan), and Mantis (Klementieff). Perhaps the biggest addition to the family, though, is Kurt Russell as Star-Lord's dad, Ego the Living Planet.

Having displayed excellent chemistry in 2014's Guardians of the Galaxy, it will no doubt be fun to see the Guardians develop more of a familial bond in Vol. 2. Since the characters have easily grown comfortable enough with each other to argue and poke fun at one another, they already seem to have the makings of what being family is all about.

Having a family element will certainly give Vol. 2 more emotional depth, and judging by first reactions at junket press screenings, the film reportedly has an unexpected profoundness to it. If audiences respond in the same way, it's a big win for Gunn, and a relatable family theme will provide him a solid foundation as he begins to write Vol. 3.

The challenge, of course, will come with how much the family's dynamic changes when the Guardians enter the world of The Avengers in Infinity War. But if the bond between the Guardians is as strong as this new behind-the-scenes look suggests, this unconventional intergalactic family should be able to stick together just fine.
