Here's how the cast of Bradley Cooper's 'Maestro' compares to the real people they're playing

"Guardians of the Galaxy," "Nightmare Alley," and "A Star is Born" actor Bradley Cooper plays Leonard Bernstein in "Maestro," and the 48-year-old is also in the director's chair for the Netflix movie.

Bernstein is renowned for his work as a composer and a conductor, and he's perhaps best known for creating the music for Jerome Robbins' "West Side Story" alongside lyricist Stephen Sondheim. He was also working on the "Candide" musical at the same time with Lillian Hellman.

Netflix's "Maestro" will focus on Bernstein's relationship with his wife, Felicia Montealegre, over the course of their lives. Cooper donned a prosthetic nose to portray Bernstein, which drew criticism online, with many accusing the project of being an example of "Jewface."

However, the composer's children released a statement saying they approved of Cooper's prosthetic and praised him for how he was approaching the biopic of their father.

Bernstein's wife, Felicia Montealegre, is played by British star Carey Mulligan – who previously starred in "Drive," "The Great Gatsby," "She Said," and "Promising Young Woman."

Montealegre was a successful actor who appeared in numerous projects on TV in the late 1940s and 1950s – including "Flowers from a Stranger," "Of Human Bondage," and "The Wings of a Dove."

Later, Montealegre would found an activist group called "Another Mother for Peace," which aimed to provide information for women about the war in Vietnam.

Her relationship with Bernstein will be the focus of "Maestro." Although the composer had affairs with men and women during their marriage, he and Montealegre would stay together until Montealegre's death in 1978.

Comedian Sarah Silverman is set to play Leonard's sister, Shirley Bernstein, in "Maestro." She was a producer who worked on several TV shows like "The Big Surprise," "Down You Go," and "The Young Set."

Shirley is also credited as an associate producer on "The Third Secret," a thriller starring Stephen Boyd, Richard Attenborough, and Jack Hawkins.

Shirley was born in 1928, and died in 1998 aged 73 – eight years after Leonard's death in 1990.

Maya Hawke will play Leonard's daughter, Jamie Bernstein, in "Maestro." Although the star has famous parents (Uma Thurman and Ethan Hawke), the 25-year-old is forging a career for herself with projects like "Stranger Things," "Do Revenge," and "Asteroid City."

Jamie Bernstein is an author and filmmaker who has been inspired by growing up surrounded by her father's music. She has since narrated numerous orchestral performances around the world, and has also written concerts aimed at younger audiences about classic composers.

She even wrote a memoir about her father, and has discussed his work on numerous occasions – including in the run-up to Steven Spielberg's "West Side Story" movie.

She told ClassicFM that she wishes her father could have seen the film and met the director "because they have a lot in common. They're both incredibly warm-hearted people." Bernstein added: "They love to reach out and communicate and make connections and they're really peas in a pod."

"West Side Story" creator and actor Jerome Robbins will be played by Michael Urie. "Ugly Betty" fans will remember him as Marc St. James – the personal assistant to Wilhemina Slater (Vanessa Williams) at Mode magazine. He can currently be seen in Apple TV+'s "Shrinking," opposite Jason Segel and Harrison Ford.

Robbins also produced "Gypsy," "Peter Pan," and "Fiddler on the Roof" over the years, and won the Academy Award for best director for the cinematic adaptation of "West Side Story" in 1961.

He continued to produce theatrical productions until shortly before his death in 1998, with "Les Noches" being his final show.
