Confined to a hospital, a dancer (Barbara Nichols) continually imagines being led to the morgue—where there’s a vacancy. Doctor: Jonathan Harris. Barney: Fredd Wayne. Morgue Nurse: Arline Sax. Day Nurse: Mary Adams. Night Nurse: Norma Connolly. Airline Agent: Wesley Lau. Ticket Clerk: Joseph Sargent. Rod Serling is the host., This videotaped Twilight Zone episode is a variation on a most familiar theme. While in the hospital recovering from a nervous breakdown, dancer Liz Powell (Barbara Nichols) is tortured by a recurring nightmare. In this nocturnal vision, Liz is escorted by a mysterious nurse (Arline Sax) to “Room 22” — the hospital morgue. The dream always ends as the nurse says insinuatingly, “Room for one more, honey.” If all this sounds familiar, it may be because the basic story was used in the 1945 British horror film Dead of Night, which in turn drew its inspiration from an anecdote in Bennett Cerf’s Famous Ghost Stories. Future Lost in Space regular Jonathan Harris also appears in “Twenty-Two,” which was adapted for television by Rod Serling and was originally telecast February 10, 1961.
