It was one of the six episodes of the second season that were shot on videotape in a short-lived experiment aimed at cutting costs, and was directed by Jack Smight.

The doctor tells the nurse it is odd that Liz, who has never seen the real morgue, knows it is room number 22.

You look for it under 'potions for bad dreams'—to be found in the Twilight Zone.The original 1906 story by E.F. Benson features a large, middle-aged male protagonist named Hugh Grainger from the English country visiting a friend in London.

He sees the same man a month later actually driving a bus that is involved in a tremendous auto accident.

The 1944 Cerf anecdote features instead a young New York woman visiting the Carolina plantation of distant relatives, with the hearse's coachman eventually revealed to be the operator of a medical building elevator that plummets when its cables break.

In the 1944 film, Dead of Night, the protagonist is again male, also with the name Hugh Grainger, haunted by a man driving a hearse, and has a premonition about a fatal bus crash.

As The Twilight Zone's second season began, the production was informed by CBS that, at about $65,000 per episode, the show was exceeding its budget.

It was decided that six consecutive episodes (production code #173-3662 through #173-3667) would be videotaped at CBS Television City in the manner of a live drama and eventually transferred to 16-millimeter film for future syndicated rebroadcasts.

Eventual savings amounted to only about $30,000 for all six entries, which was judged to be insufficient to offset the loss of depth of visual perspective that, at the time, only film could offer.

The shows wound up looking little better than set-bound soap operas and, as a result, the experiment was deemed a failure and never tried again.
