#Q ORIGINAL QUESTION

Regarding the film Star Wars: The Last Jedi (2017), who was the oldest cast member at time of filming, how old were they, and what was their role?

What a correct answer would look like:

The oldest credited cast member in Star Wars: The Last Jedi (2017) was Andrew Jack (born January 28, 1944), who was 72 years old during filming. He played Major Ematt (a Resistance officer, notably seen in the trenches on Crait). While Frank Oz (born May 25, 1944) returned to voice and puppeteer Yoda, he was slightly younger (71 when filming began, turning 72 during production). Peter Mayhew (born May 19, 1944) was also older than Oz but was credited only as "Chewbacca Consultant" and did not perform the role.

Specific Details:

Role Specifics and Production Detail:

Frank Oz provided both the voice and the puppeteering for Yoda, who appears as a Force spirit to Luke Skywalker on the planet Ahch-To. In a departure from the prequel trilogy (where Yoda was primarily a CGI character), director Rian Johnson wanted to return to the aesthetic of the original trilogy. Consequently, a new practical puppet was created using the original molds from 1980’s The Empire Strikes Back.

Oz's involvement was one of the production's most closely guarded secrets; to keep his return a surprise, his name was omitted from much of the pre-release marketing and credit lists. He performed on set at Pinewood Studios, working directly with Mark Hamill to recreate the master-student dynamic seen decades earlier.

Other Veteran Cast Members:

While other veteran actors from the franchise are part of the broader sequel trilogy, Frank Oz was the oldest performer to appear in The Last Jedi.
