TCM’s prime-time schedule tonight presents two stunningly photographed and imaginatively framed and sculpted movies from the 1970s. First up: 1972’s Cabaret, Bob Fosse’s tour de force of choreography and film direction, which handed Liza Minnelli the role of a lifetime. Which she, in turn, devoured. Joel Grey, as the emcee, is fabulous as well – though on Broadway in two revivals, Alan Cumming has been spectacular enough to claim ownership of the role. No one’s really done that, before or since, with Minnelli’s interpretation of Sally Bowles.
