"One of my favorite episodes was Hans Conreid’s turn as the Japanese sailor who reached the island by midget sub and took everyone prisoner because he thought The War was still on."

The Japanese sailor was played by character actor Vito Scotti. Hans Conreid was in two separate episodes as disoriented biplane pilot Wrongway Feldman.

And they both played Major Bonacelli on Hogan’s Heroes.

You’re right. My mistake.

Vitto Scotti was also played the crazy scientist in a couple more episodes who abducted the castaways to perform mind-swapping experiments and later to turn the castaways into zombie-slaves who muttered “I hear and I obey…” with a plan to rob Fort Knox.
