Drama based on a true story. George Reeves (Ben Affleck) was a journeyman actor who had played a small role in 'Gone With the Wind' and appeared on screen with the likes of James Cagney, Rita Hayworth and Marlene Dietrich, but his career was not exactly booming when he was cast as comic book hero Superman in a 1951 B-movie, 'Superman and the Mole Men'. A year later, the producers of the movie launched a syndicated Superman television series with Reeves returning as the Man of Steel. The show became a major hit, and Reeves was a star at last. However, on June 16, 1959, to the shock of many, Reeves was found dead of a gunshot wound. Police soon declared Reeves' death a suicide and closed the case, but his mother (Lois Smith) refused to believe her son took his own life, and hired Louis Simo (Adrien Brody), a private detective, to find out the truth about her son's passing.
