The restored "Cabaret" is opening the TCM Classic Film Festival that runs Thursday to Sunday in Los Angeles. Liza Minnelli and Joel Grey, the movie's stars, were scheduled to attend the ceremony marking the movie's 40th anniversary.
Minnelli's turn as cabaret singer Sally Bowles captured a best actress Academy Award and cemented her young stardom. She said making "Cabaret" was a joyful "secret," filmed in Munich and far away from meddling Los Angeles studio bosses.
Other TCM film festival events include a tribute to "Vertigo" star Kim Novak.
TCM said it expects to air the restored "Cabaret" later this year.
