Casanova Brown (1944)

Casanova Brown (Gary Cooper) is about to marry Madge (Anita Louise) when he learns that his former wife, Isabel (Teresa Wright), has just had a baby that belongs to him, and plans to put the child up for adoption. Casanova runs out on the wedding, disguises himself as a doctor, visits the hospital where his infant daughter is being held and runs off with her to a hotel, where he does his best to care for the baby. Before long, Madge and Isabel hunt down Casanova, whom they are both furious with.
