American actor who played Morn, the silent barfly who became one of Deep Space Nine's best-loved background characters.
Mark Allen Shepherd is an American actor, born in 1961, best known for playing Morn on Star Trek: Deep Space Nine. A fixture at the bar in Quark's establishment through all seven seasons, Morn became a running joke because other characters described him as endlessly talkative, while he never spoke on screen.
Shepherd also appeared as Morn, without credit, in one episode each of The Next Generation and Voyager, making the character one of the few to cross all three series of the era.
