Sporting a fur coat and pixie cut, a bubbly Liza Minnelli shows up halfway through the first episode of FXs Fosse/Verdon, clutching her tiny dog and smiling as she greets choreographer and director Bob Fosse at a production party in Munich, Germany. Bobby, darling, she says. Ive been counting down the hours for this day to arrive. Soon enough, shes wearing blue eyeshadow and a tiny black ensemble, doing high kicks in front of the cameras as she belts out the musical number Mein Herr.

Of course, it isnt actually Liza Minnelli were witnessing, but stage actress Kelli Barrett, playing the daughter of Judy Garland during her Oscar-winning run as Sally Bowles in 1972s movie-musical Cabaret.

Barrett was given the daunting task of channeling one of the most well-known performers in Hollywood history in Fosse/Verdon , an eight-episode limited series that details the romantic and creative partnership between womanizing dance maestro Fosse (Sam Rockwell) and his charming muse Gwen Verdon (Michelle Williams) over five decades. Its a story seen through the keen eyes of theater masters Thomas Kail, Steven Levenson, Joel Fields and Lin-Manuel Miranda.
