10 MORE Actors You Didn’t Know Were In Star Trek

Stephen Root has been in so many things, you'll get RSI just by scrolling down his IMDB page. Emmy-nominated for his recent role as Monroe Fuches in the Bill Hader dark comedy Barry, Root was also the 'Man in the High Castle' in The Man in the High Castle, Bill and Buck in King of the Hill, and Bob Mayer in The West Wing. His list of films includes Get Out, No Country for Old Men, and (personal pleasure) Bicentennial Man.

Root might not necessarily be a household name in spite of all that, but he is a household face — one dodging balls and/or wrenches! In 1991, Root added Star Trek to his dictionary definition of 'prolific career' — in the seminal two-parter Unification, no less. You'd be forgiven for not recognising Root as Captain K'Vada. Under all that Klingon make-up and gruffness, the Florida-born actor proved his chameleon-esque talents once more.

As well as providing the Bird-of-Prey bus to Romulus in Unification, K'Vada did his best to make a bad journey of it for Picard and Data. His misanthropic (mis-an-Klingon?) mood is explained as the result of a shoulder injury in Jeri Taylor's novelisation of the episodes. K'Vada dies a warrior's death in the Star Trek: Klingon Empire novel Honor Bound, but he's still alive in canon. Perhaps Root might "piggy… back" for a return!
