The Wild Wild West
In 1968, Martin broke his leg and then suffered a near-fatal heart attack, forcing "The Wild Wild West" to replace him with other actors, including Charles Aidman, William Schallert and Alan Hale Jr for nine episodes. He was nominated for an Emmy Award for Outstanding Lead Actor in a Drama Series, for the fourth and final season of "The Wild Wild West". The series was cancelled in 1969 in the midst of a national controversy over violence on television.
