AYes. Director John Ford was not very happy with this film, and one day he told Hepburn to direct a scene - which she did, and this movie marks her debut as a director.
AMary of Scotland is considered to be a historical drama, a sub-genre of fiction that portrays fictional accounts or dramatizes historical figures or events. Whereas the names, dates, places, and familial relationships may be accurate, the portrayal of events, causes, and interpersonal relationships is fictionalized. For example, Mary is depicted as a victim to Scotland and a martyr to her love for Bothwell, whereas Elizabeth is depicted as cold, vain, and jealous of her cousin. In actuality, the rivalry between them had to do with the warring factions of Protestantism and Catholicism, a reason that is mentioned only cursorily throughout the movie. John Knox (played by Moroni Olsen) rants against Mary because she is a "jezebel of France". In actuality, John Knox was the leader of the Protestant Reformation in Scotland and spoke against Mary because she was a devout Catholic. Bothwell is depicted as a romantic figure whereas some historians claim that it was he who murdered Lord Darnley, then kidnapped Mary and carried her off to Dunbar Castle where he raped her. Finally, the finale in which Elizabeth and Mary come face-to-face is said to be inaccurate as there is no evidence that the two queens ever met.
