Becket is a 1964 historical drama film based on the play "Becket or the Honour of God" by Jean Anouilh. It stars Richard Burton as Thomas Becket and Peter O'Toole as King Henry II. The film follows the relationship between the two men, beginning as close friends and ending as sworn enemies.
After his appointment to Archbishop of Canterbury, Becket begins to challenge Henry's authority and support the Church's independence, leading to a series of political and religious conflicts. As tensions rise between the two, Henry makes a careless remark about Becket, which is misinterpreted by his followers as an order to kill him.
In a dramatic confrontation, Becket refuses to bow to Henry's demands and is ultimately murdered by knights loyal to the king. The film ends with Henry's remorse over Becket's death and his admission of guilt for causing it.
Becket received widespread critical acclaim upon its release, earning 12 Academy Award nominations and winning for Best Adapted Screenplay. The performances of Burton and O'Toole were particularly praised, with O'Toole's portrayal of Henry II considered one of the best of his career.
