Christine Norden replaced Rosalyn Boulter after an intervention by Burgess Meredith's wife Paulette Goddard, who decided that Boulter wasn't sexy enough.
Burgess Meredith was suffering long-running psychiatric problems of his own during production and sought advice from the doctor who was this movie's Technical Adviser. According to his autobiography, the psychiatrist advised him to try having children, which, in fact, proved to be a helpful solution.
Burgess Meredith had come to Britain because his wife of the time, Paulette Goddard, was starring in Alexander Korda's An Ideal Husband (1947). The marriage was in trouble and Meredith didn't want to be apart from her. Korda's company, London Films, was also producing this movie, and Korda offered Meredith the lead. (The character is said to be Canadian, rather than English, as in the novel).
This movie was first telecast in Los Angeles, California on Sunday, November 15, 1953 on KTLA (Channel 5) and in New York City on Sunday, April 4, 1954 on WCBS (Channel 2). In San Francisco, California it made its television debut on Thursday, June 9, 1955 on KPIX (Channel 5).
