The Academy Award for Best Original Screenplay is the Academy Award (also known as an Oscar) for the best screenplay not based upon previously published material. It was created in 1940 as a separate writing award from the Academy Award for Best Story. Beginning with the Oscars for 1957, the two categories were combined to honor only the screenplay.
