I'm curious if there is any data on the man who played Nik Sant (now Captain Rex) in ROTJ. This polaroid gives him the initial and last name of L. Burner, but nothing about him is known, including his first name. If he wasn't a high-profile actor, and just an extra, there's a good chance he lived in the Crescent City, CA area, but this is by no means a given.
While Filoni liked the idea of making him Captain Rex, this was never actually settled on - so currently they are still two different characters with different Wookieepedia pages. https://starwars.fandom.com/wiki/Nik_Sant The similarities between Sant's appearance and that of the former clone captain Rex, a character who appears in both the "Star Wars: The Clone Wars and Star Wars Rebels television series, stoked speculation that Sant and Rex could be the same character. In 2016, at a screening of the second season finale of Star Wars Rebels, executive producer Dave Filoni speculated that the "bearded old guy on Endor," Nik Sant, could be Rex, suggesting it did not make any sense for there to be an "old guy" on Endor unless it was someone like Rex.[7] The Rebels series finale, which aired on March 5, 2018, confirmed that Rex did fight at the Battle of Endor, but did not go so far as to confirm that Rex and Sant are the same character.[8] Six months after the episode's airing, Filoni revealed in an interview with IGN he ultimately chose to not canonize the theory because he felt that laying down an already established character prior to his coming to Star Wars wasn't correct, adding that Rex could have been present at Endor and not be Sant, even though some fans could choose to believe that Sant and Rex are the same individual while others choose to not do so.[9] In recreations of shots from Return of the Jedi in the Star Wars Galaxy of Adventures short "Han Solo - From Smuggler to General," Rex is used instead of Sant wearing clone trooper armor. Rex also appears in original shots in the short.[10] Because Galaxy of Adventures shorts are not meant to be taken as literal events,[11] no official source has currently definitively stated that Sant and Rex are the same character.
It's a conspiracy! When Temuera Morrison is 72 years old, he will go back in time to play that guy. Then, it will finally be revealed that it was Rex all along
