Girls Will Be Boys is a 1934 British comedy film by French director Marcel Varnel and starring Dolly Haas, Cyril Maude and Esmond Knight. It is based on The Last Lord, a play by Kurt Siodmak. The film was shot at Elstree Studios with sets designed by the art director Cedric Dawe. Haas made this, her first English-language film, following a Nazi-led riot at the premiere of her previous film Das häßliche Mädchen. The riots protested the male lead, Max Hansen, who was supposedly "too Jewish." In 1936, Haas fled Germany altogether.
