Darvi was born Bajla Węgier to Jewish parents Chajm Węgier, a baker, and his wife, Chaja. She had three brothers, Robert, Jacques, and Jean-Isidore, and a sister, Sura. When the Germans invaded France during World War Two, Darvi's mother fled to southern France with her sister and two brothers. Darvi decided to stay in Paris for her education along with her brother Robert. Both were eventually jailed by the Vichy government due to their Polish background. She was fifteen years old. Robert died in a concentration camp. "I had the usual experiences of hunger and humiliation, and I try not to think of them and discuss them but I can never forget them," she later said. Darvi's mother secured her release after three years, in 1943. She went to stay with her mother near Toulouse. "We were always under threat on account of us being Polish," she said. Her elder sister was a model and she did some modelling. She married a businessman, Alban Cavalcade, on October 7, 1950 and traveled with him to Monaco.
While on the French Riviera she became associated with Virginia and Darryl Zanuck.. She was separated from Cavalcade at the time. The Zanucks invited her to come to Los Angeles and in 1952 she moved there to live with them. She shared a room with Zanuck's second daughter, Susan. She changed her name to Bella Darvi, Darvi being a combination of the first names of Zanuck and his wife, Virginia. She took acting lessons. In February 1953 it was announced she had signed a long term contract with 20th Century Fox. Hedda Hopper called her "an exciting new personality". Eventually, she became Zanuck's mistress, although she reportedly dated other men including Robert Stack and Brad Dexter.

In March 1953 Leonard Goldstein was reportedly writing The Daughter of Mata Hari as a vehicle for her. In December 1953 she was announced for the role of Nefer, the seductive Babylonian courtesan, in The Egyptian over Ava Gardner. Hedda Hopper predicted Darvi would be one of the "stars of 1954" and "make a splash" in her first film. The International Press of Hollywood announced she was one of their "stars of tomorrow" along with Hugh O'Brian, Pat Crowley, Steve Forrest, Barbara Rush and Richard Egan. Hell and High Water came out in February. The New York Times said Darvi "does not succeed convincingly." From February to June 1954 she made The Egyptian. Fox then announced her for The Racers. She was publicly linked with Brad Dexter around this time. The Racers started filming in September 1954. In November 1954 she left Hollywood to return to Paris. "I was guilty of egomania," Zanuck later said about trying to build Darvi into a star.

She made a film in France with Eddie Constantine, Je suis un sentimental. Zanuck left his wife for Darvi, but left her when he discovered that she was bisexual. In 1956, she reportedly lost $1,000 in two minutes at the casino then $65,000 in two days. She made I'll Get Back to Kandara in France.
