 In the scene where Terry (Marlon Brando) and Edie (Eva Marie Saint)  are talking on the rooftop of Terrys apartment building, after he  finds his pigeons killed, Terry looks off to his left, with the next  shot (showing what hes looking at) of the Hudson River and  Manhattan in the distance. In that shot, a large ocean liner is seen  moving down the Hudson on its way out to sea. The ship is the then  new Italian liner Andrea Doria, a little more than two years before  it was sunk in a collision with the Swedish liner Stockholm off  Marthas Vineyard.
