Debut of British actress Shirley Anne Field; she was 17. Before getting into acting, she was a model, including posing nude and semi-nude in men's magazines as a young teen. She had offers for film roles later in her career that required nudity, but refused. She said posing for naked photos was a necessity to survive at the time; she didn't need to do it in films.
This was Kay Kendall's last film completely made (i.e., interiors and exteriors) in the UK. (Her last four were either completely filmed abroad, or at least had foreign exteriors.)
Actress Muriel Geoge's final film.
In the original BBC teleplay Simon and Laura (1955), Esma Cannon had played Jessie the maid. Here she is cast in the more minor rôle of Laura's North-Eastern fan.
