It's Love I'm After (1937 Archie Mayo)

Fun romantic comedy in which vain actor Leslie Howard is tempted away from love-hate relationship with Bette Davis to help friend's son Patric Knowles in his relationship with Olivia de Havilland, who's fallen for the actor. All helped along enormously by faithful manservant Eric Blore and his bird impressions.

A Warner Bros. film, written by Casey Robinson and Maurice Hanline, shot by James Van Trees, also featuring George Barbier (The Man Who Came to Dinner), Bonita Granville (Now Voyager - ended up a Lassie TV producer!), Spring Byington, EE Clive.

Casey Robinson was already credited on dozens of films before this. He went on to write Now Voyager, Kings Row, Dark Victory, The Old Maid, All This And Heaven Too and Passage to Marseille.
