 The second Commando Cody serial, which actually had Leonard Nimoy as a Martian zombie in Chapter 11 in an underwater cave scene. Now, was that Radar Men on the Moon, or is that a different one? No, no, that's the first one. That's Radar Men from the Moon. That was Reddick the Moon Menace. That was the first Commando Cody. My other favorite serial was Drums of Fu Manchu.
