She would make most of her major movies in Frnace, becoming great friends with actors like Michel Piccoli, Yves Montand and Simone Signoret. She also made occasional English-speaking roles such as What's New Pussycat? and Good Neighbor Sam. Although Romy and Delon eventually split, they remained lifelong friends, starring together in movies like La Piscine (The Swimming Pool) and The Assassination Of Trotsky. She would win two Cesars, the French version of Oscars, in her career. The tragic death of her son at age 14 led to depression and an alcohol problem. Many sections of the press alleged Romy's untimely death in 1982 was a suicide from a cocktail of alcohol and sleeping pills. But a post mortem ruled the cause as cardiac arrest. Readers of Le Parisien newspaper voted her the greatest actress of all time in 1999.
