Based on Christopher Isherwood's Goodbye to Berlin and John Van Druten's dramatization of it, I Am a Camera, Cabaret is set in Weimar-era Berlin as American writer Clifford Bradshaw arrives to work on his novel and soak up the debaucherous nightlife. He meets English cabaret performer Sally Bowles and a complex relationship develops, all as the Nazis ascend to power and the spectre of World War II and all its horrors loom on the horizon.

The creative team also includes choreographer Julia Cheng; club, set, and costume designer Tom Scutt; lighting designer Isabella Byrd; sound designer Nick Lidster (for Autograph); and music supervisor and director Jennifer Whyte. Hair and wig design are by Sam Cox, and Guy Common is handling makeup design. Prologue composition and music direction are by Angus MacRae, with Jordan Fein serving as prologue director. Casting is by Bernard Telsey and Kristian Charbonier, and Thomas Recktenwald serves as production stage manager.
