Wikipedia: Martial arts film

A film genre originated in the [Pacific Rim]?. This genre of film is one kind of action film characterized by extensive fighting scenes employing various types of martial arts. This genre should not be limited to Asian films. There are many action movies by well known western martial artists such as Steven Segal and Jean Claude van Damme.

Martial Arts film stars can be classified in two types, namely genuine martial artists who pursued a filming career vs dancers and actors who acted in martial arts film under the directions of choreographers.

Martial arts film stars who are martial artists on their own merits:

[Bruce Lee]?'s "[Enter the dragon]?" (1973) was one of the films that brought the genre into mainstream Western acceptance.
[Jackie Chan]? continued this crossover during the 80s and 90s, finaly conquering the US market with [Rumble in the Bronx]? (1995) and the two [Rush Hour]? films.
