Kung Fu (1972)
1 mistake in King of the Mountain
Starring: David Carradine, Keye Luke, Philip Ahn, Radames Pera
Trivia: "Kung Fu" was not canceled due to poor ratings, as it performed solidly during its run. It was canceled due to the physical stress and abuse on David Carradine's body, and it was wearing him out.
