Carter does one of his rare yet chilling Hitler impersonations in this episode. Actor Larry Hovis appears as Hitler without Carter's customary black gloves, which he insisted on wearing during filming to hide his real-life wedding ring. Since Hitler was officially married, the gloveless scene works.
Reply: Hitler did not marry Eva Braun until the night before their mutual suicides about a week before Germany's surrender. Prior to that, he was never married and his relationship with Eva was kept strictly under wraps. The German people believed he was a dedicated servant married only to Germany - an image he wanted to maintain. Most had no idea she even existed until after her death when the marriage became known. Consequently, Hitler would have never appeared in public wearing a wedding ring during the time this episode takes place.
