Gruff, gravel-voiced Lawrence Tierney (1919-2002) was a "tough guy" character actor from the heydey of film noir gangster movies who appreared twice in Star Trek. Predictably, he played holo-mobster Cyrus Redblock from the fictional 1940s world of detective Dixon Hill in TNG's "The Big Goodbye", and later was the alien Regent of Palamar in DS9's "Business as Usual."
