Mercedes McCambridge: From Oscar Glory to The Exorcist’s Demon

Carlotta Mercedes Agnes McCambridge came into the world in Joliet, Illinois, on March 16, 1916. After studying at Mundelein College in Chicago, she established herself in the 1940s as a leading radio voice, when the medium represented the primary entertainment in American homes. That radio experience forged her vocal abilities and prepared her for a film career that would begin in striking fashion.

Her big screen debut occurred in 1949 with “All the King’s Men,” where Robert Rossen directed her in the adaptation of Robert Penn Warren’s novel. McCambridge played Sadie Burke, the cynical assistant to politician Willie Stark, and that debut immediately earned her the Oscar for Best Supporting Actress. The statuette arrived at her first film attempt, a rare case in Academy history.

Specialization in roles of determined and morally complex women characterized her subsequent path. In 1954 Nicholas Ray cast her in “Johnny Guitar” alongside Joan Crawford, an anomalous western where McCambridge embodied Emma Small, an obsessive and vindictive figure who became iconic. Professional tensions between the two actresses on set ended up in the chronicles of the time, with Crawford manifesting impatience toward her colleague. The film acquired cult status over the years.

Two years later, George Stevens called her for “Giant,” a Texan saga with Elizabeth Taylor, Rock Hudson and James Dean in his final performance. McCambridge wore the clothes of Luz Benedict, the protagonist’s authoritarian sister, and that performance earned her a second Oscar nomination. The character confirmed her aptitude for constructing female figures with layered psychology.

The most singular collaboration arrived in 1973, when William Friedkin entrusted her with dubbing the demonic voice in “The Exorcist.” McCambridge never appeared on screen, but her guttural voice became the film’s most disturbing sonic element. To obtain that effect, she smoked cigarettes and swallowed raw eggs during recordings, while sound technicians further modified the audio tracks. Her name did not initially appear in the credits, a circumstance that led her to legal action concluded with the insertion of the credit in subsequent versions.

Her career continued between cinema and television until the 1990s. In 1987 her private life suffered a tragedy when her son John Markle killed his wife and daughters before taking his own life. McCambridge publicly addressed what happened in the following years, speaking about mental health. She passed away in La Jolla, California, on March 2, 2004, a few weeks before turning eighty-eight. Her filmography crosses genres and decades, with a voice that remains recognizable in every performance.
