What to Know About ‘Maestro’: A Guide to Bradley Cooper’s Bernstein Biopic

How much of the film’s score is Bernstein’s music?

That cue you hear when Bernstein finds out he’ll be making his conducting debut at the New York Philharmonic? That’s from “On the Waterfront,” the 1954 Marlon Brando drama for which Bernstein wrote the music. That spiky, horn-filled composition that signals tension when Bernstein and a male lover arrive at the family’s Connecticut home? That’s the prologue from “West Side Story.”

In fact, most of the music you hear was written by Bernstein. (Also see if you can spot classical excerpts from his ballets “Facsimile” and “Fancy Free,” his opera “A Quiet Place,” and parts of his second and third symphonies.)

His personal life

Was Bernstein gay or bisexual?

Though he was married to his wife, the actress Felicia Montealegre (Carey Mulligan), for 26 years, he had numerous relationships — with both men and women — before and during their marriage, and after her death in 1978.

The film focuses on two of them — his dalliance with the clarinetist David Oppenheim (Matt Bomer), whose bottom Bernstein slaps at the beginning of the film, and the musician Tom Cothran (Gideon Glick), whom he steals kisses with at a party and brings to his Connecticut home.

What was society’s attitude toward gay people at the time?

Anti-gay prejudice was rampant in America in the 1940s and 1950s, and the Lavender Scare — a fear that homosexual people had infiltrated the federal government and were a threat to national security — led to the dismissal of gay and lesbian employees, and those assumed to be, en masse. Gay, lesbian and transgender people — particularly public figures — faced intense pressure to conceal their identities, and Bernstein worried that the public revelation of his sexual orientation would hurt his conducting prospects.

Did Montealegre know Bernstein was gay or bisexual when she married him?

Yes, according to a letter she wrote to him the year after they were married, which the couple’s children discovered after her death. “You are a homosexual and may never change,” she wrote, adding later, “I am willing to accept you as you are, without being a martyr.” She went on to tell him, “Let’s try and see what happens if you are free to do as you like, but without guilt and confession.”
