Puccini's Il Trittico, a collection of three brief operas from the Royal Opera House, screens at "Opera in Cinema" at the West End Cinema. Sung in Italian, the stories Il Tabarro, Suor Angelica and Gianni Schicchi range from heartbreaking drama to satire. The Independent writes, "The accepted wisdom on Puccini’s trio of one-acters, Il Trittico, is that Gianni Schicchi is the masterpiece, Suor Angelica of very particular and questionable taste, with Il Tabarro, all shadow and melodrama, bringing up the rear." 7 p.m. Italian, subtitled.
