Lee also favored cross-training between different fighting styles, and had a particular interest in grappling. After befriending accomplished grappler Gene LeBell on the set of "The Green Hornet", Lee offered to teach him striking arts in exchange for being taught judo and wrestling techniques. He also trained with other judokas in Seattle and California, and expressed to LeBell a wish to integrate judo into his fighting style. Although Lee opined grappling was of little use on action choreography because it was not visually distinctive, he did showcase grappling moves in his own films, such as "Way of the Dragon", where his character finishes his opponent with a neck hold inspired by LeBell, and "Enter the Dragon", whose prologue features Lee submitting an opponent with an armbar.
