Directing

Robert Radler

A director of action-oriented fare, Robert Radler helmed dozens of episodes in the "Power Rangers" franchise, along with numerous martial arts productions. Radler's first film, the 1989 taekwondo movie "Best of the Best," starring Eric Roberts and Phillip Rhee, was enough of a success to warrant a sequel, and shortly thereafter he signed on to direct installments of the mid-1990s hit show "Mighty Morphin' Power Rangers." Following the series to its subsequent incarnation, "Power Rangers Zeo," he eventually worked his way back to films, helming "The Substitute 3: Winner Takes All" and its 2001 sequel, both featuring Treat Williams in action-hero mode.
