The stars were out in force at the after-party of the Palm Springs International Film Festival Awards Gala at the Parker Palm Springs on Thursday night.
The biopic premiered at the prestigious Venice Film Festival in September, where it earned a 7-minute standing ovation, but it has not been with controversy.
The biographical drama film follows the longtime relationship between conductor-composer Leonard Bernstein and actress Felicia Montealegre Cohn Bernstein.
Leonard Bernstein and Felicia Montealegre's children open up about 'Maestro,' how their mom knew about their dad's bisexuality and how it affected her.
