Mr. Howell Impostor

Trivia

 * The imposter Mr. Howell 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.
 * In scenes where camera movement is required the use of stand-ins, tight shots, obscured views and/or rubber masks were used.
