Academy Award for Best Original Screenplay

The Academy Award for Best Original Screenplay is the Academy Award for the best screenplay not based upon previously published material; writers with "written by", "screenplay" or "story" credits are all collectively recognized as recipients for each nomination.
The category was created in 1940, and has always existed concurrently with the Best Adapted Screenplay category ; originally, it also co-existed with a third writing category, Best Story, which had been active since the original Academy Awards ceremony in 1929; this latter award was meant to reward specifically writers who originated a film's plot and characters rather than those who wrote the dialogue and final screenplay, although Best Story would later be merged into Best Original Screenplay in 1956.

Eligibility

Screenplays are eligible if they are not based on "previously published material". The Writer's Branch of the academy determines if a screenplay is adapted or original, based on possible sources in question, interviews given about the film and the film's publicity materials, and sometimes places screenplays in a different category than the Writers Guild of America. For the 75th Academy Awards, Gangs of New York was nominated as an original screenplay despite being based on the book The Gangs of New York because the writers based the film on the book's historical research but largely invented the characters and plot. For the 89th Academy Awards, Moonlight was campaigned as an original screenplay, being based on an unpublished play, but was ultimately placed in the adapted screenplay category, which it won. Similarly, Whiplash was considered an adapted screenplay at the 87th Academy Awards despite being written as an original screenplay because a scene from the script was produced as a proof-of-concept short film. However, 2008's Frozen River, which similarly had a proof-of-concept short film screened at film festivals, was nominated as an original screenplay.
