She attended Saint Joan of Arc College and later the Conservatoire de Paris, where she performed dramatic roles.
She made her film debut when she was still in school. Jean Cocteau cast her in an uncredited role as a tall ballerina in Testament of Orpheus (1960). When she was on holiday in Nassau, writer-producer Kevin McClory saw her and recommended that she audition for his film Thunderball (1965).
The role of Domino was originally to be an Italian woman, Dominetta Petacchi.
Auger impressed the producers so much that they rewrote the part to that of a French woman, to better suit Auger. Although she took lessons to perfect her English, her voice was eventually dubbed by Nikki van der Zyl.
Auger would claim that she related to her character Domino, as she and Domino were involved with older mentor The most immediate byproduct of Claudine"s stardom was a semi-nude Playboy spread.
Thunderball launched Auger into a successful European movie career, but did little for her otherwise in the United States.
She did however star in a Danny Thomas Special called ‘The Road to Lebanon’ with Bing Crosby which was shown on National Broadcasting Company on April 20, 1966. In 1968, she co-starred with another Bond girl Ursula Andress in the Italian comedy Anyone Can Play. In 1971, she starred with two other Bond girls, Barbara Bach and Barbara Bouchet, in Black Belly of the Tarantula, a giallo mystery.
She had some roles in European films as Triple Cross (1966) (reuniting her with her James Bond director Terence Young) and The Killing Game (1967).
