Standing six-foot-11, character actor Dennis Ott's unusual height made him ideal for playing space aliens and menacing types. Though his career looked promising, it was cut short by AIDS. His film roles include that of the Devil in Bill and Ted's Bogus Journey (1991), a Klingon in Star Trek III: The Search for Spock (1984), and an alien in Star Trek VI: The Undiscovered Country (1991). ~ Sandra Brennan, All Movie Guide
