Black Sunday is the powerful story of a Black September terrorist group attempting to blow up a Goodyear blimp hovering over the Super Bowl stadium with 80,000 people and the President of the United States in attendance. Robert Shaw plays an Israeli commando who discovers the plot, masterminded by Marthe Keller with the help of deranged Vietnam veteran Bruce Dern. Director John Frankenheimer creates a chilling portrait of people obsessed with a cause for which they will die. In the exciting finale, Dern and Keller navigate the lethal airship into the terror-stricken stadium, pursued by Shaw in a helicopter, climaxing one of the most unusual chases in movie history.
