UPDATE - 10/13@9:54AM: Reader Robert M notes that Kerry Von Erich's nickname was The Modern Day Warrior and he used Tom Sawyer as walk out music.
The Iron Claw is an upcoming film from A24 which tells the story of the Von Erich brothers, who made history in the intensely competitive world of professional wrestling in the early 1980s. A new trailer for the film was released yesterday and it prominently features Rush's Tom Sawyer starting around the 50-second mark and continuing throughout. The film will be released on December 22nd, and you can watch the trailer below or on YouTube at this location. Thanks to Phil Simon for the heads up.
