Guardians of the Galaxy Vol. 2 may be just a month away from its May 5 release, but there’s still new material coming out from the set to promote the highly anticipated sequel. The latest trailer for Vol. 2 may be the last one, but that hasn’t stopped the cast from continuing to share info and promotional content to build more anticipation. Much of the buzz surrounding the actors has been about the addition of legendary action star Kurt Russell as Ego The Living Planet, the father of Chris Pratt’s Peter Quill.

Needless to say, Pratt was excited to work with Russell on Guardians of the Galaxy Vol. 2. Writer/director James Gunn said that Pratt suggested he cast Russell in the role of Ego in the first place and that the star would have been disappointed if he didn’t. So it should come as no surprise that when shown on the set in-between takes with Russell, Pratt would cease to be Star-Lord and turn into a total fanboy.

Pratt shared a brief video clip to his Instagram page on Friday, posing and smiling with Russell on the set of Guardians 2 with both in full costume and sets and blue screens clearly visible in the background.

“Kurt Russell poses with a fan on the set of [Guardians of the Galaxy Vol. 2],” the caption of Pratt’s Instagram post reads. Pratt is keenly self-aware about his Russell fandom and has previously talked at length about the relationship between Star-Lord and his long lost father as one of the driving forces of the movie, so there’s a good chance that the star will show a lot of visceral emotion in his scenes with Russell as Ego.

Guardians 2 has long been billed as a “story about fathers,” with Russell as Ego at the center of it. Pratt said in a previous interview that making Vol. 2 helped him deal with his real-life father’s death, so clearly felt that casting Russell would be the perfect choice for him to help channel his complex emotions into effective scenes with the veteran actor. If this new set video is any indication, the two surely enjoyed working with each other on the sequel – hopefully that chemistry translates into the final product.

As excited as Pratt was to work with Russell on Vol. 2, it’s unclear how long his time with the action legend will be. Russell suggested in the past that his future in the Marvel Cinematic Universe is uncertain, but Gunn said recently that Russell’s Ego is a big part of the franchise and will appear in future MCU films. It’s possible that Russell had a change of heart since his non-committal prior comments, or that Marvel have adjusted their plans to keep Ego around.
