is a 1966 American comedy film released by Walt Disney Productions,[3] and starring Dick Van Dyke as a U.S. Navy pilot who becomes a castaway on a tropical island.

[5] While flying a routine mission for the U.S. Navy from his aircraft carrier, an emergency causes Lieutenant Robin "Rob" Crusoe (Van Dyke), a Naval Aviator, to eject from his F-8 Crusader into the ocean.

He builds a shelter for himself, fashions new clothing out of available materials, and begins to scout the island, discovering an abandoned Japanese submarine from World War II.

[6] Using tools and blueprints found in the submarine, Crusoe and Floyd construct a Japanese pavilion, a golf course, and a mail delivery system for sending bottles containing missives to his fiancee out to sea.

Wednesday recounts that due to her unwillingness to marry, her chieftain father, Tanamashuhi (Akim Tamiroff), plans to sacrifice her and her sisters to Kaboona, an immense effigy on the island with whom he pretends to communicate.

Intended as a wacky modern-day simulation of the Daniel Defoe classic, it might have borne up in reduced running-time but in its present far-overlength 115 minutes misses as sustained entertainment.

"[13] Kevin Thomas of the Los Angeles Times wrote that "sophisticated parents might want to stay away", but Dick Van Dyke was "both ingratiating and funny" in the title role.
