During the Marvel Studios San Diego Comic-Con Hall H panel, they showed the crowd a sizzle reel of footage for GUARDIANS OF THE GALAXY VOL. 2. In this footage — which remains to be seen if it will be released publicly — revealed that actor Kurt Russell is in fact the father of Chris Pratt's Peter Quill, a.k.a. Star-Lord (WHO?!).
Russell is portraying Ego, who, in the comics, is a planet entity and it remains to be seen how this will transition and adapt into the Marvel Cinematic Universe at the time this post was published. As more info is made available, DailySuperHero.com will update you.
