Like many New York actors, Martin Kove was willing to go unbilled to pick up extra paychecks in such East Coast-filmed efforts as Little Murders (1971) and Last House on the Left (1972). By 1984, Kove was pulling down third billing in such films as The Karate Kid, wherein he played Kreese, the bad karate expert who trained the film's principal heavy William Zabka for his bout against the simon-pure Ralph Macchio (Kove replaced Chuck Norris, who turned down the role of Kreese because he didn't want karate trainers to be shown in an unsympathetic light).
Martin Kove's work on series TV has included the roles of detective Victor Isbecki on Cagney and Lacey and an extraterrestrial named Jesse on Hard Time on Planet Earth. ~ Hal Erickson, All Movie Guide.
