Jack Kelly plays a dual role in this episode--Bart Maverick and double Rod Claxton. He'd earlier played a dual role in Pappy.
Dawn Wells would later play Mary Ann on Gilligan's Island.
In this episode we learn that Bart knows Morse Code and Semaphore.
Nice guest shots by Dawn Wells and Gerald Mohr are the highlights of this one. If there's one downside it's that Bart's double, Rod Claxton, doesn't get very much screen time to flesh out the character.
