Glengarry, Hedwig, and Maria

A close competition over at the American Theatre Facebook page, where today's question is: What's the best film adaptation of a play or musical?

UPDATE: My favorite answer so far, from Tim Doyle:

My pick would have to be "Saving Private Ryan" (1998) based on the 1949 Yip Harburg/Burton Lane musical "Normandy, Schmormondy."
