Mr. Howell Impostor

Bio
The Imposter is an unidentified con-artist who has had plastic surgery to resemble millionaire industrialist Thurston Howell III. His real name is unknown, but he used his new face to steal Mr. Howell's identity and take over his position as CEO and chief stock-holder of Howell Industries, claiming he was the only survivor of the S.S. Minnow. Once in control of the company and its assets, he started selling off its stocks and properties for money which he spent in large amounts on female companions. During a cruise in the South Pacific, he was lost overboard carrying a champagne bottle and a lady's shoe. He ended up washing up on the island with the Castaways and was stunned to learn that the real Mr. Howell was still alive. For unknown reasons, he knocked out Mr. Howell and took over his identity on the island, confusing Mrs. Howell, the Skipper and Gilligan in the process. However, after the Professor revealed that the imposter had been outed back home, the fraudulent Mr. Howell fled the island in Mr. Howell's clothes and his real wallet in the back pocket. It is likely he was arrested after being picked up in the ocean and sent to prison.

Trivia

 * The Mr. Howell Imposter is of course played by Jim Backus. The visual effect of having Jim Backus play both Mr. Howell and the imposter is called "Split-Screen," whereby the same scene is filmed twice with the actor in each place at separate times. Split-Screen relies on the camera being fixed in place. Many of these techniques were repeated in Gilligan vs. Gilligan and All About Eva.
 * In scenes where camera movement is required, the show employed the use of stand-ins, tight shots, obscured views and/or the use of rubber masks.
