CBS Radio Mystery Theater

CBS Radio Mystery Theater (a.k.a. Radio Mystery Theater and Mystery Theater, sometimes abbreviated as CBSRMT) is a radio drama series created by Himan Brown that was broadcast on CBS Radio Network affiliates from 1974 to 1982, and later in the early 2000s was repeated by the NPR satellite feed.

The format was similar to that of classic old time radio shows like The Mysterious Traveler and The Whistler, in that the episodes were introduced by host E. G. Marshall who provided pithy wisdom and commentary throughout. Unlike the hosts of those earlier programs, Marshall is fully mortal, merely someone whose heightened insight and erudition plunge the listener into the world of the macabre.

As with Himan Brown's prior Inner Sanctum Mysteries, each episode of CBS Radio Mystery Theater opened and closed with the ominous sound of a creaking door. This sound effect is accompanied by Marshall's greeting, "Come in!… Welcome. I'm E. G. Marshall." At each show's conclusion, the door swings shut, and Marshall signs off with: "Until next time, pleasant… dreams?" This is followed by an extended variation of the show's theme music.

CBSRMT was broadcast each weeknight, at first with a new program each night. Later in the run, three or four episodes were new originals each week, and the remainder repeats. There were 1,399 original episodes. The total number of broadcasts, including repeats, was 2,969. Each episode was allotted a full hour of airtime, but after commercials and newscasts, each episode typically ran for around 45 minutes.

Hosts
E. G. Marshall hosted the program from January 1974 until February 1, 1982, when actress Tammy Grimes took over for the remainder of the series' final season, maintaining the format. Himan Brown re-recorded E. G. Marshall's original host segments for NPR's broadcast of the show in the 2000s.

Music
The series' theme music features three descending notes from double basses, a stopped horn sting and timpani roll, then a low, eerie theme played by the bass clarinet. The opening and closing themes for CBSRMT are excerpted from the music from the score for Twilight Zone episode "Two", composed by Nathan Van Cleave. Series listeners will immediately recognize the "RMT Theme" beginning about 1:35 on the "Two" soundtrack selection from the Twilight Zone CD boxed set. Other background tracks from the Twilight Zone music library, to which CBS owned full rights, were featured repeatedly in episodes of CBSRMT. The theme song and the other music was also previously used in the 1950s and 1960s in other CBS-owned radio and television dramas (Perry Mason; Rawhide; The Fugitive; Gunsmoke; Have Gun Will Travel; Suspense; Yours Truly, Johnny Dollar; etc.), in addition to Twilight Zone, as it was all owned by CBS.

Scope
Despite the show's title, Brown expanded its scope beyond mysteries to include horror, science fiction, historical drama, westerns and comedy, along with seasonal dramas during the Christmas season: An adaptation of A Christmas Carol, starring host E.G. Marshall as Scrooge, was broadcast every Christmas Eve with the exception of 1974 and 1982.

In addition to original stories, there were adaptations of classic tales by such writers as O. Henry, Ambrose Bierce, Algernon Blackwood, Wilkie Collins, Arthur Conan Doyle, Charles Dickens, H. Rider Haggard, Henry James, Guy de Maupassant, Edith Wharton, Oscar Wilde and others. Brown typically devoted the first full week of each January to a five- or seven-part series on a common theme. These included a full week of stories by an American writer, (Edgar Allan Poe in 1975, Mark Twain in 1976); week-long adaptations of classic novels (The Last Days of Pompeii in 1980, Les Misérables in 1982); and original dramas about historical figures (Nefertiti in 1979, Alexander the Great in 1981). The works of Russian writers, including Gogol, Dostoevsky and Tolstoy, were also adapted.

Criticism
Radio historian John Dunning has criticized the quality of the show's script writing, arguing that Brown used writers for many scripts "who were by their nature performers" rather than writers.

When the program began in 1974, actors were paid union scale; at the time around $73.92 per episode. Writers earned a flat rate of $350 per episode. Production took place with assembly-line precision. Brown met with actors at 9:00 a.m. for the first script reading. After roles were assigned, recording began. By noon, the recording of the actors was complete, and Brown handed everyone checks. The program was taped in New York at the CBS Studio Building, 49 East 52nd Street in Studio G, formerly Studio 27 (renamed Studio 'G' in honor of Arthur Godfrey whose programs originated in the building for decades).

Continuing popularity
From June 3 to November 27, 1998, CBSRMT was rebroadcast over CBS radio affiliates and, in 2000, on some NPR stations, in both cases, Himan Brown re-recorded the original introduction and narrations of E.G. Marshall and Tammy Grimes.

CBSRMT remains popular with listeners of audio drama, with numerous websites and podcasts devoted to the series. All episodes are available, and many recordings include original network and local news and commercials, providing insights into the period in which the episodes were broadcast.
