The Iron Duke is a 1934 British historical film directed by Victor Saville and starring George Arliss, Ellaline Terriss and Gladys Cooper.

[1] With Napoleon defeated and exiled, the reluctant Duke of Wellington is persuaded by Lord Castelreagh to represent Great Britain's interests at the Congress of Vienna, where the victorious allies will decide the future of Europe.

While there, his friend the Duchess of Richmond introduces the married man to the pretty Lady Frances Webster, an ardent admirer, at her ball.

[2] The New York Times reviewer wrote, "The Iron Duke can be recommended to Mr. Arliss's admirers everywhere as a pseudo-historical drama which manages to be both impressive and amusing and which reveals the star at his very best".

"[4] More recently, TV Guide gave the film two out of four stars, and wrote, "Not only are the pace and direction of The Iron Duke uninspired and haphazard, but the script is rife with historical inaccuracies, the glossing over of less flattering events, and definite misrepresentation in the case of Marshal Ney's (Willard) execution".
