Margot Grahame (20 February 1911 – 1 January 1982) was an English actress most noted for starring in The Informer and The Crimson Pirate. She started acting in 1930 and made her last screen appearance in 1958. Her family went to South Africa when she was three years old, which led to her being educated there. She began her stage career with Dennis Neilson-Terry a few weeks after leaving school at the age of 14, in Pretoria. She made her London stage debut in 1927 as understudy to Mary Glynne in The Terror. Her screen debut was in the 1930 film Rookery Nook. Grahame was the highest-paid actress in England during the 1930s, before going to America, where she performed in a number of films of the '30s, '40s and '50s. Hollywood producers' interest was piqued that she had appeared in forty-two major roles in English films in only three years. Grahame was signed to a long-term contract by RKO. She appeared as the prostitute girlfriend of Gypo Nolan in John Ford's The Informer (1935). She followed this performance with a role as leading lady Milady de Winter in The Three Musketeers (1935). She performed with Bebe Daniels in The Fabulous Joe (1947).
