American actor who played the ruthless Klingon commander Kruge in The Search for Spock.
Christopher Lloyd (born 1938) is an American actor known for larger-than-life characters, most famously Doc Brown in the Back to the Future trilogy and Reverend Jim Ignatowski in the sitcom Taxi.
In Star Trek III: The Search for Spock (1984) Lloyd played Commander Kruge, a Klingon who seeks the secret of the Genesis Device. Kruge's crew kills Kirk's son David Marcus, and Kirk takes over Kruge's Bird-of-Prey after defeating him in hand-to-hand combat on the dying Genesis Planet. The captured ship carries the crew for the rest of the film and into The Voyage Home.
