Margaux Hemingway, 22, emphasizes a point in talking with her sister Mariel Hemingway, 14, during lunch at Joe’s Pier 52 on April 2, 1976. Both sisters appear in the new film Lipstick, a story about what a rape victim does in retribution. Their dad was Jack Hemingway; grandpa was the Nobel Prize winning author Ernest Hemingway. Ernest shot himself to death at age 61 in 1961; Margaux killed herself with a drug overdose at age 41 in 1996. Mariel has written about her family’s “suicide curse.”
