Two-time Star Trek guest actor Lawrence Tierney passed away this week at the age of 82. Tierney played the holographic villain "Cyrus Redblock" in the Star Trek: The Next Generation episode "The Big Goodbye." Years later he appeared in Star Trek: Deep Space Nine as the "Regent of Palamar," who tries to buy arms from an associate of Quark's in "Business as Usual."

Tierney died in his sleep Tuesday at a Los Angeles nursing home, according to the Associated Press.

The veteran actor's Star Trek roles mirrored the many tough-guy characters he played during the 1940s and '50s, such as the bad guy who caused the train wreck in Cecil B. DeMille's 1952 best-picture Oscar-winner, "The Greatest Show on Earth." Throughout his 80-film career, Tierney perfected many gangster roles, but he is probably best known for the title role in the 1945 B-movie classic "Dillinger" and the leader of a group of killers in Quentin Tarantino's 1992 crime drama "Reservoir Dogs."
