In Hollywood she appeared in B-movies such as 'Guns Don't Argue' and 'The Monster of PiedrasBlancas'. She played both brassy platinum-blondes and (with her natural dark hair) sultry Spanish women. Carmen'ssmoldering good looks, hourglass figure, and striking green eyes quickly landed her on the big screen in 1956 playing a feisty Spanish senorita named "Serelda" in the film 'The Three Outlaws', a Westernbased on the same events as the later 'Butch Cassidy and the Sundance Kid', and co-starring Neville Brand and Alan Hale, Jr as Butch and Sundance. She was then cast by producer/director Howard W. Koch as an Indian girl in 'War Drums' alongside Lex Barker ofTarzan fame. Koch took a liking to Carmen and cast her in his next film for Warner Bros, the teenage rock 'n' roll juvenile delinquent themed 'Untamed Youth' (1957), co-starring Rockabilly legend Eddie Cochran, which inspired Cochran to cover the song "Jeannie,Jeannie, Jeannie" for her.
Carmen also appeared as a femme fatale in 'Portland Expose' alongside Frank Gorshin who later gained fame as the "Riddler" on the Batman TV series. She also appeared in the 'Three Stooges' short subject 'A Merry Mix Up' playing Joe Besser'sgirlfriend "Mary". The short is notable for the Stooges playing three sets of identical triplets.
In 1998, Carmen was the subject of a TV biography titled "Jeanne Carmen: Queen of the B-Movies," on the series 'E! True Hollywood Story'. The show stated that Carmen maintained a "dangerously close friendship with Marilyn Monroe and TheKennedys" and that after the death of Monroe, Carmen was told to leave town by JohnnyRosselli who was working for Chicago Mob Boss Sam Giancana. Believing her life was in danger, she fled to Scottsdale, Arizona, where she lived incognito for more than a decade. Carmen abandoned her platinum-blonde locks, had threechildren and lived a quiet life, never mentioning her prior life in Hollywood.
Carmen's last published interview was on November 21, 2007, by SX News, an Australian weekly gay and lesbian newspaper.
