Spielberg recalled the infamously malfunctioning mechanical shark that they used in the 1975 film "Jaws." "The shark was the first real prima-donna actor I ever worked with," the director said. "He wouldn't do anything I told him to do. It was designed to jump out of the water like Flipper and work its jaws and roll its eyes and flap its tail and almost walk up on shore and shake your hand. As it turned out, the shark could barely make a right-hand turn and could never go left. When it submerged, bubbles came up.... we tested it for the first time during first-unit principal photography. It cruised along, and right in front of everybody sank thirty feet to the sandy bottom – and never came up."
