Ray Walston, who played the lovable extraterrestrial Uncle Martin on the 1960s sitcom “My Favorite Martian” and the devil in the Broadway musical “Damn Yankees,” has died. He was 86. In “My Favorite Martian,” Walston played opposite Bill Bixby as a Martian stranded on Earth. His antennae-sprouting alien character masqueraded as Bixby’s “Uncle Martin” and spent most of his time trying to conceal his identity from curious Earthlings.
