Cooper, 47, also directs the movie, his followup to “A Star is Born.” It co-stars Carey Mulligan as Bernstein’s wife, Felicia Montealegre, and Jeremy Strong (Kendall Roy in “Succession”) as critic John Gruen.
The new publicity photos also show Cooper as a younger Bernstein, sharing a smile with Mulligan’s Montealegre.
A legend in the world of musical theater, Bernstein was best known for composing the music for “West Side Story,” the 1957 Broadway show that spawned the 1961 film and Steven Spielberg’s recent remake. He died in 1990 at age 72.
