Personal life
In 1928, Selznick began an on-again off-again affair with Jean Arthur, one of the actresses under contract at Paramount while he was an executive there. Simultaneously he was dating Irene Gladys Mayer, daughter of MGM mogul Louis B. Mayer.
In 1930, Selznick married Mayer and after living in a series of rented houses they moved into an estate in Beverly Hills, California. It was purchased for them by Mayer's father and designed by architect Roland Coate in 1933–1934. They separated in 1945 and divorced in 1948. They had two sons, Jeffrey Selznick (1932–1997) and Daniel Selznick (1936–2024). Daniel, who died in August 2024, would serve as an executive at Universal Pictures for four years and also produced the television mini-series Blood Feud and Hoover vs. The Kennedys, among others, and theatrical productions such The Man with the Perfect Wife.
In 1949, he married actress Jennifer Jones, whom he had discovered early in her career and mentored. They had one daughter, Mary Jennifer Selznick (1954–1976), who died by suicide by jumping from a 22nd-floor window in Los Angeles on May 11, 1976.
Selznick was an amphetamine user, and often dictated long, rambling memos to his directors, writers, investors, staff and stars. The documentary Shadowing The Third Man relates that Selznick introduced The Third Man director Carol Reed to the use of amphetamines, which allowed Reed to bring the picture in below budget and on schedule by filming nearly 22 hours at a time.
Selznick was a Republican. On October 18, 1944, the Hollywood Committee, led by Selznick and Cecil B. DeMille, held the Hollywood for Dewey Rally in the Los Angeles Coliseum in support of the Dewey-Bricker ticket, as well as Governor Earl Warren of California, who was Dewey's running mate in 1948. The gathering drew 93,000, with Lionel Barrymore as the master of ceremonies and short speeches by Hedda Hopper and Walt Disney.
