All of the actors whose characters were ballet dancers: Marisa Berenson, Robert Torti, Adrian Paul, and Nancy Valen all had their dance scenes performed by professional dancers. Indeed, Berenson and Valen wore flat practice slippers with ribbons tied like the ribbons of pointe or toeshoes but never did Berenson or Valen perform on pointe wearing toeshoes. Obvious differences such as the body types of Torti and Paul are noticeable in scenes portrayed by their dance doubles and Torti's hairstyle, height, and musculature are noticeably different between the actor and his dance double and Valen and her dance double. Members of the San Francisco Ballet stepped in as dance doubles and extras for the episode.
The Los Angeles Orpheum theater, originally built as a combination vaudeville and feature film venue, located on the South end of the theatrical Broadway Main Street, has been used for television locations. The Orpheum was where the "Gumm (Garland) Sisters were performing their vaudeville act in 1935 when Busby Berkeley was told by his MGM Boss, "catch their act, report if the kids should get an audition!" .... Berkeley drove from the studio, parking in the lot across the street, buying a ticket at the box office, entering the theater to wait, and then catch their act! Returning to MGM the same afternoon, Berkeley reported to Louis B. Mayer, and arranged with their mother to bring the sisters to the Culver City Studio for a meeting and audition. Afterwards, the sisters were signed to a contract, appearing in a short musical filmed in Santa Barbara, California. "Murder, She Wrote -Danse Diabolical" used the theater because the stage had an under stage with a stage trap opening centered in the stage's middle floor.
