Luke and Kylo Ren are two of the characters in Battlefront II who aren't voiced by the original actors.
Temuera Morrison played Jango Fett in the prequel movies but has played Boba Fett in a few Star Wars games prior to Battlefront II. He’s also lent his voice to the F.E.A.R and Condemned games. He played characters in Wolfenstein II, Dota 2, Bayonetta 2, Sleeping Dogs, and Uncharted 4. Speaking of Fett, the bald man overlooking the Tatooine sunset at the end of the episode is almost certainly Boba Fett himself. He also voiced Boba in the 2006 game Star Wars: Empire at War, and DICE's Star Wars Battlefront (2015) and Battlefront II (2017), the latter of which were produced by EA.
