A Man for All Seasons is a 1966 film based on Robert Bolt's play A Man for All Seasons about Sir Thomas More. It was released on 12 December 1966. Paul Scofield, who had played More in the West End stage premiere, also took the role in the film. It was directed by Fred Zinnemann, who had previously directed such films as High Noon and From Here to Eternity. The film won six Academy Awards, including Best Picture and Best Actor.

The title reflects playwright Bolt’s portrayal of More as the ultimate man of conscience and as remaining true to his principles and religion under all circumstances and at all times. Bolt borrowed the title from Robert Whittington, a contemporary of More, who in 1520 wrote of him:

Sir Thomas More was the 16th-century Lord Chancellor of England who refused to sign a letter asking Pope Clement VII to annul the King's marriage to Catherine of Aragon and resigned rather than take an Oath of Supremacy declaring the King the Supreme Head of the Church of England. The King is Henry VIII of England and his wife is Catherine of Aragon, the first of Henry's eventual six wives. Both the play and the film portray More as a tragic hero, motivated by his devout Roman Catholic faith and envied by rivals, such as Thomas Cromwell. He is also deeply loved by his family and respected by the common people.
