Near the end, James West (Robert Conrad) introduces the woman he is with as Nancy Conrad, which is the name of his real-life daughter.
One of the very few western stories ever made without a single horse. As was another episode, Night Of The Simian Terror, which also took place in a remote island.
Ross Martin (Artemus Gordon), appears in credit only as he was recovering from a heart attack.
The shot of the bow of the boat weathering the storm at night in the beginning looks to be the same shot as the boat in the intro to Gilligan's Island
The opening scenes of the boat in the storm are the same shots of the Minnow being tossed about in the opening of Gilligan's Island.
