Captain Boycott is a 1947 British historical drama film directed by Frank Launder and starring Stewart Granger, Kathleen Ryan, Mervyn Johns, Alastair Sim and Cecil Parker. Robert Donat makes a cameo appearance as the Irish nationalist leader Charles Stewart Parnell. The film explains how the word boycott appeared in the English language. Ironically, the titular character plays a secondary role in the film, as an anti-hero, and the hero of the film is Hugh Davin.

Plot

In 1880 in County Mayo, during the period of Irish history known as the Land War, Irish tenant farmers agitated for reinstatement of their former lower rents and increased tenants' rights, especially from absentee English landlords. They particularly resented evictions. Some resorted to the gun to achieve justice, but others, inspired by the Irish statesman Charles Stewart Parnell (played in a brief cameo role by Robert Donat), shunned violence and adopted a form of passive resistance.
