Real Steel is a 2011 American science fiction sports film starring Hugh Jackman and Dakota Goyo and co-produced and directed by Shawn Levy for DreamWorks Pictures. The film is based on the short story "Steel", written by Richard Matheson, which was originally published in the May 1956 edition of The Magazine of Fantasy & Science Fiction, and later adapted into a 1963 Twilight Zone episode. The film features a former boxer (Jackman) whose sport is now played by robots. He must build and train his own robot with his son. Real Steel was in development for several years before production began on June 24, 2010. Filming took place primarily in the U.S. state of Michigan. Animatronic robots were built for the film, and motion capture technology was used to depict the rodeo brawling of the robots.
