SDCC: James Gunn Explains Why "Guardians of the Galaxy Vol. 2" Footage Isn't Being Released

In addition to appearances from Gunn and the cast, the panel featured a teaser reel of footage including a scene with Yondu (Michael Rooker), Rocket and Baby Groot, as well as more trailer-style moments. Unlike other footage that was released shortly after it debuted in San Diego, Marvel has yet to make the "Vol. 2" footage available online. The reason? Gunn is a self-proclaimed "perfectionist" and the visual effects are still in the early stages.

"Everything needs to be exactly the way I want it to be, to be seen in a film, so that it stands up to repeated viewings," said Gunn. Both he and Marvel aren't "comfortable" with the footage being released to the public just yet, but assured fans that it will be released, when ready, at some point.

Gunn compared the screening of the footage at SDCC to showing a friend a piece of film that he might have been working on that his house. One viewing of a piece of an "in-progress" film to an excited audience is one thing, releasing it to the public at large is something else entirely.

Gunn also reiterated for fans that Kurt Russell is playing Peter Quill's dad, Ego the Living Planet. Created by Stan Lee and Jack Kirby, Ego first appeared in "Thor" #132 (September 1966). Without getting into specifics, Gunn reassures that how a living planet can procreate with a human woman will be explained.

Gunn also confirmed that actor Sylvester Stallone has a role in the upcoming sequel, calling him "fantastic."

Answering a few fan questions in the video, Gunn also addressed Yondu's metal fin, seen in Rooker's appearance on the panel and during the SDCC footage. According to the director, Yondu gets the fin from Baby Groot. Exactly how he get it still remains to be seen. Gunn also confirmed that Baby Groot will be wearing a Ravager uniform at one point, one given to him by the group of mercenaries.

"Guardians of the Galaxy Vol. 2" starring Chris Pratt, Kurt Russell, Zoe Saldana, Vin Diesel and Dave Bautista lands in theaters May 2017.
