Hailed in ads as the “Picture of the Generation,” Frank Lloyd’s 1933 historical family epic, Cavalcade, took home the Academy Award for Best Picture, along with trophies for Best Art Direction (William S. Darling) and Best Director. The tale of the British Marryott clan from 1899 to 1933, the film was based on the 1931 play by Noël Coward and adapted by Russian screenwriter Sonya Levien (State Fair, Oklahoma!) and Hollywood scribe Reginald Berkeley (Dreyfus). Featuring songs by Coward, George M. Cohan, and others, the film earned a Best Actress nod for Diana Wynyard as family matriarch Jane Marryot and also stars Clive Brook, Una O’Connor, and Bonita Granville. The only Best Picture winner not available as a single DVD — it’s part of a three-volume Fox seventy-fifth anniversary package — Cavalcade will get a rare public screening tonight at the Monday Nights with Oscar series at the Academy Theater, hosted by Brad Rosenstein, curator of the exhibition “Star Quality: The World of Noël Coward,” on view at the New York Public Library for the Performing Arts at Lincoln Center through August 18. The screening and the display are part of the Noël Coward in New York festival, which continues with a series of special events including lectures, live performances, staged readings, and a master class at Juilliard.
