Trivia

When auditioning for the role of Martok for "Star Trek: Deep Space Nine" (1993), the casting director told him to show more anger so he threw a chair at a wall. The display cost him a thumbnail, but won him the role.

Good-natured, yet violent outbursts against furniture seem to be a specialty of his. During an interview for a German public access channel he demonstrated what an outside linebacker (his position in college football) is, by suddenly throwing a table over.

He became an active fighter in finding a cure for sclerodermia (a lethal disease of the skin) after his father died of it.

Along with Jeffrey Combs, Randy Oglesby and Thomas Kopache, he is one of only four actors to play seven different characters on "Star Trek." He played the Vulcan captain of the U.S.S. Saratoga, General/Chancellor Martok, Roy Rittenhouse and Laas in "Star Trek: Deep Space Nine" (1993), an Hirogen hunter in "Star Trek: Voyager" (1995) and Kolos and a Klingon captain in "Star Trek: Enterprise" (2001)).

He portrayed a record-breaking eighth unique character on "Star Trek" when he played Kovol in Star Trek: Of Gods and Men (2007) (V).
