Since a Leonard Bernstein biopic, Maestro, is now available on Netflix, audiences may be curious about his true story and relationship with his wife, Felicia. As reports suggest, Martin Scorsese was initially going to direct Maestro. However, after he stepped away from the project to take over as The Irishman's director, Steven Spielberg offered Bradley Cooper the part after watching A Star is Born. The rest is history. Not only has Bradley Cooper starred in the film as the titular Maestro, but he also helmed it, making it his first directorial endeavor after his debut with A Star is Born.
