Step Lively (1944)

Producer Gordon Miller (George Murphy) and his profligate actors are staying at a New York City hotel, where they're living the high life as they plan to mount a stage show. Alas, they have no money to pay their bills, and hotel boss Wagner (Adolphe Menjou) will banish them unless he gets paid. Joining the parade of those about to be bilked by Miller is Glenn Russell (Frank Sinatra), a playwright whose stellar singing just might be enough to right the fortunes of all involved.
