Patrick Stewart has a select but notable body of work as a voice actor in English-dubbed Japanese anime, bringing his distinguished and authoritative vocal presence to two prominent animated films from celebrated directors.

His career in this specific field includes providing the voice for the character Lloyd Steam in the 2004 Japanese animated feature Steamboy, directed by Katsuhiro Otomo. In this retro-science fiction epic set in Victorian England, Stewart voiced the role of the eccentric and brilliant inventor grandfather to the young protagonist, Ray Steam. The film was noted for its elaborate animation and large-scale production.

In addition to this role, Stewart voiced Lord Yupa in the English dub of the 1984 Hayao Miyazaki film Nausicaä of the Valley of the Wind. This post-apocalyptic fantasy adventure, a classic of the medium, featured Stewart as the skilled and noble swordmaster, a mentor figure to the film's protagonist. This performance was part of the film's 2005 Disney-produced English dub, which assembled a cast of well-known actors. These two roles represent his primary work within the anime genre as an English voice actor.
