The W Plan is a 1930 British spy film produced and directed by Victor Saville and starring Brian Aherne, Madeleine Carroll, Gibb McLaughlin, and Gordon Harker. The screenplay was written by Saville with Miles Malleson and Frank Launder, based on the novel of the same name by Graham Seton. When the film was released in the United States, Aherne was appearing in The Barretts of Wimpole Street on Broadway, and receiving praise for his performance as Robert Browning. The film was a critical success, but did not do well at the box office.
