The first footage from Guardians Of The Galaxy 2 was released during the San Diego Comic-Con (SDCC) 2016 but Marvel chose not to make the teaser available online.

This was a huge let-down for millions of fans who couldn't make it to SDCC. James Gunn, who is helming the extraterrestrial superhero movie, has the perfect explanation. During a Facebook question-answer session with fans the director of the Marvel movie claims that he wants the public to see the "finished" version of the clippings.

"Of course, I want to share everything with you guys, it's important to me to be able to do that. But here's the thing: the footage we released at Comic-Con will eventually be seen by the public but in a more finished form," he said in the Facebook live video.

The 45-year-old American screenwriter and director also cited the ongoing filming and visual effects editing as reasons to why the trailer remains unfinished. "It's very early days, we've only been stopped shooting for a month... The visual effects are not finished. I am a perfectionist. People who follow me know that everything needs to be exactly how I want it to be to be seen in a film, so that it stands up to repeated viewings. And the truth is this Comic-Con footage... it's not something that I nor Marvel are comfortable with being out there and standing up to repeated viewings. The visual effects just aren't finished. If I do something, I want to do it 100% correctly. However, to sit in the audience one time with an excited crowd and show them an in-progress piece of film, it's a different story."

Warning: Spoilers Ahead

The cosmic adventure of Star-Lord/Peter Quill and his team of misfits will take a new turn in the sequel as the mysteries of the Star-Lord's true parentage will be revealed. The Comic-Con footage has reportedly spoilt the secret already and in its report, Gizmodo has revealed the name.

In the second part, Kurt Russell enters the galaxy as Ego, popular as the Living Planet in the Marvel Comics. If reports are to be believed, he is the father of Peter Quill. Here is the first look of Russel's character shared by Marvel's vice president Ryan Penagos.

Guardians Of The Galaxy Vol 2 will release on 5 May 2017 and the cast includes, Chris Pratt as Star-Lord/Peter Quill, Zoe Saldana as Gamora, Dave Bautista as Drax the Destroyer. Bradley Cooper and Vin Diesel will return to voice Rocket Raccoon and Groot.
