Moss Hart wrote the first draft of Once in a Lifetime, a comedy about Hollywood’s transition to “talkies”, as a 25-year-old unknown. Established playwright George S. Kaufman helped revise it into a Broadway hit. Steve Vineberg calls it the “the finest comedy ever written by Americans”, and discusses how it began a long successful collaboration between the two writers. Still making theatergoers laugh in the 21st century, the 1930 play joins the public domain in 8 days. #PublicDomainDayCountdown
