The Broadway revival of William Finn and James Lapine’s Tony-winning Falsettos — about a family who, struggling to remain “tight-knit,” eventually redefine what family means in difficult times — is now playing on Broadway at the Walter Kerr Theatre. The cast is headed by two-time Tony Award winner Christian Borle as Marvin, Tony nominee Stephanie J. Block as Trina, and Tony nominee Andrew Rannells as Whizzer, with Tracie Thoms as Dr. Charlotte, Betsy Wolfe as Cordelia, Tony nominee Brandon Uranowitz as Mendel, and Anthony Rosenthal as Jason.
