3-D effects were created by Montreal-based Sensio.
In the original telecast of this episode, the opening sequence featuring Rod Serling was taken from his introduction for "Twilight Zone, The" (1959) {The Midnight Sun (#3.10)}. For purposes of this "special 3-D episode", Serling's voice was overdubbed by an impressionist (Mark Silverman), for obvious reasons.
In promoting his voice appearance as Rod Serling in is episode, NBC said that Mark Silverman "is the only voice artist recognized by the Serling estate."
Robert Duncan McNeill specifically asked to direct this episode when he learned part of it was going to be in 3D.
Various scenes of this episode were shot in 3-D.
