‘Star Wars’ actor Peter Sumner, 74

LOS ANGELES — Peter Sumner, an Australian actor who had a small but memorable part as an officer on the Death Star in “Star Wars,” has died at age 74, his agent confirmed Wednesday.

The actor worked only two days on the 1977 film, playing Lieutenant Pol Treidum. While the name might not ring a bell for casual fans, his line, “TK-421, do you copy” likely will. It was enough to make him a fan convention mainstay. According to the Sydney Morning Herald, which first reported his death, he was also the only Australian actor to appear in the film.

Sumner also appeared in Tony Richardson’s “Ned Kelly,” the children’s show “Play School” and other Australian series like “Spyforce” and “Heartbreak High.”
