Susan Backlinie, Swimmer Who Was First Victim in ‘Jaws,’ Dies at 77

The actress and stunt woman Susan Backlinie, whose portrayal of a violent death as the first shark attack victim in the opening scene of the blockbuster movie “Jaws” terrified moviegoers, died on Saturday. She was 77.

Ms. Backlinie died at her home in California, her agent, Sean Clark, said on Sunday. He said she had a heart attack.

“Jaws,” the 1975 movie directed by Steven Spielberg, memorably features Ms. Backlinie in a scene in which she played a skinny-dipper, Chrissie Watkins, who runs along the beach and dives into the water for a nighttime swim.

The placid scene is shattered as she is suddenly pulled under the water. She screams while being violently thrashed by an unseen great white shark and tries desperately to cling to a clanging buoy only to be pulled below the water one final time.

For the scene, Ms. Backlinie was secured to a harness, according to The Daily Jaws website. The Palm Beach Post reported that Ms. Backlinie was wearing a pair of jeans with metal plates stitched into the sides with cables attached.
