Trivia: With his short slender build, large brown eyes, and abundant hair, actor Ralph Macchio has often appeared to be the perennial adolescent -- a fact that has sometimes hindered his career. The actor is best known for his work in the phenomenally popular Karate Kid (1984), in which the then twenty-two year old actor played a troubled 14-year-old boy who is helped by a sage karate instructor. Macchio has been in show business most of his life; born in Long Island, he began performing in local musical productions as a young teenager. At 16, he began working in TV commercials, and before he had even graduated from high school had appeared in the adolescent comedy Up the Academy (1980), though he did not appear in another film until working in Francis Ford Coppola's epic of teenage rivalry The Outsiders (1983). Following the Karate Kid, Macchio began working in a series of minor films, such as the successful My Cousin Vinny (1992). He continued to work on television and on stage, even after his teen heart-throb days were over, appearing on Broadway opposite Robert De Niro in 1986 in Cuba and His Teddy Bears. He also appeared in the next two Karate Kid sequels, along with films like Dangerous Company and Too Much Sun. In 2002, Macchio tried his hand at screenwriting and directing, both helming and penning the short film Love Thy Brother. In 2006, the actor took a comedic turn in the sports comedy Beer League. Macchio would remain active for years to come, appearing most notably on the popular series Ugly Betty.

Trivia: 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.
