Daisy Ridley’s Rey and Adam Driver’s Kylo Ren are front and center, alongside co-stars Mark Hamill, John Boyega and the late Carrie Fisher, in the new trailer for ‘Star Wars: The Last Jedi.’

When Han Solo and Chewbacca walked back onto the Millennium Falcon in Star Wars: The Force Awakens, it was a homecoming for two iconic movie characters — and a memorable first day of work for the big rookie in the furry suit.

Mayhew couldn’t walk well on the set of Force Awakens because he was still recovering from a pair of knee replacements, so Suotamo became his stunt double and transitioned to doing more on Last Jedi, which included a Wookiee boot camp. Mayhew “talked about the mindset of Chewie, how he’s loyal to his pilot — things that require underlining,” Suotamo says. And the new guy needed some work: “He told me I was too skinny to be a Wookiee.”
