Many famous movie actors are associated with a particularly punchy line or memorable monologue; some are even synonymous with a single spectacular shot. Susan Backlinie won herself a spot in film history largely on the strength of a single yelp of surprise: At the beginning of Steven Spielberg’s classic thriller Jaws, after the character played by Backlinie ill-advisedly goes on an after-dark skinny-dipping jaunt just off the coast of the Atlantic, Backlinie gasps as she is tugged on by an unseen shark. 

So terrifying is this moment — and so identified has it become with the film that surrounds it — that when Turner Classic Movies asked filmmaker Chuck Workman to assemble a montage of great movies from the art form’s first 100 years, he chose Backlinie’s startling expression of shock as the moment that would stand in for the entirety of Jaws. We didn’t need to see any scenes with the stars Richard Dreyfuss, Roy Scheider, or Robert Shaw; all that was required to identify the movie was Backlinie’s iconic reaction to her sudden, shocking encounter with a shark.
