Kim Kahana, the stunt performer, teacher, coordinator and war hero who played Chongo on the kids show Danger Island and doubled for Charles Bronson in several action films, has died. He was 94.

Kahana died Monday of natural causes at his home in Groveland, Florida, his wife, Sandy Kahana, told The Hollywood Reporter.

Kahana, 5-foot-7 and 150 pounds, taught stunts to many thousands of students since the mid-1970s in six-week courses that took place in Chatsworth, California, and Central Florida. Many went on to have thriving careers in show business.

He also had six different black belt degrees — he taught martial arts, too — and worked as a professional bodyguard protecting Hollywood types.

A native of Hawaii, Kahana appeared in his first film as a biker in the Marlon Brando-starring The Wild One (1953) and was an extra in other movies before he realized that stunt performers got paid more than he did.
