The Municipal Theatre of St. Louis, affectionately known as The Muny, has been a part of St. Louis life for generations. This summer marked the 100th season that The Muny has presented top-notch musical theater outdoors in St. Louis’ Forest Park, and “The Best of Us” pays tribute to this world-renowned institution on that significant anniversary. Featuring dozens of interviews with actors, performers, craftspeople, and audience members and providing rare glimpses backstage, the film demonstrates why The Muny is a place like no other.
