Spencer Milligan departed the show at the beginning of its third season for financial reasons. In addition to a salary increase, he believed the rest of the cast and he should receive compensation for using their images on various merchandise. His character, Rick Marshall, was replaced by his brother, Jack Marshall, played by actor Ron Harper. Milligan did not return for the brief scene, also shown in the credits of the third season, showing Rick Marshall being transported out of the "Land of the Lost". One of the show's crew played the role, instead, wearing a wig resembling Milligan's hair and standing with his back to the camera.
