David Hemmings, a renowned English actor and director, contributed a notable voice performance to the medium of anime late in his career. While his professional life was primarily defined by his work in live-action film and television, his involvement in anime represents a distinct and recognized entry in his diverse body of work.

Hemmings' most significant, and apparently only, credit as an anime voice actor came in 1981 for the film Swan Lake. This animated feature, formally titled Sekai Meisaku Dōwa Hakuchō no Mizūmi, was a Japanese production by Toei Animation, created in partnership with the Soviet Union's Soyuzmultfilm. For its release in English-speaking markets, a special English dub was produced that featured well-known actors in the principal roles. In this version, distributed by The Samuel Goldwyn Company, David Hemmings provided the voice for the film's primary antagonist, the evil sorcerer Rothbart.

This English-language adaptation of Swan Lake was notable for casting celebrities rather than regular voice actors, with Hemmings joining a cast that included Christopher Atkins as Prince Siegfried and Pam Dawber as Princess Odette. Hemmings' performance as the villainous Rothbart was part of this effort to bring a higher profile to the animated feature. His work on the film has been noted by viewers, with some reviews highlighting the voice talents in the English version as a reason to seek it out. This voice role stands as a unique intersection between Hemmings's established career in film and the world of animated storytelling. Outside of this specific and well-documented role, there is no available information to suggest he had a broader career as an anime voice actor or any recurring collaborations within the anime industry. His other acting credits remain firmly in live-action, with memorable roles in films such as Blowup, Barbarella, Gladiator, and Gangs of New York, as well as extensive work as a television director in the 1980s.
