American Screenwriters Association was founded in 1996 by John E. Johnson in Cincinnati, OH. the organization in response to the void he perceived between emerging screenwriters and the industry. A short four years later, ASA had grown to 650+ members in 8 countries.
John's career started while lunching with a friend in Wilmington, NC. John overheard an assistant producer discussing the need for more extras on a movie being filmed there, Simple Justice, starring Andre Braugher, Samuel L. Jackson and James Avery. Interrupting their conversation John talked his way into a featured extra role playing a court reporter, photographer and spectator. He was a casting assistant for the independent movie This Train. John wrote numerous screenplays (To No Avail, The True Life Adventures of Mr. and Mrs. Fish, The Last Time I Saw Eve, Christmas on Jane Street) and radio dramas, and eventually formed the American Screenwriters Association (ASA).
ASA hosts the ASA International Screenwriters Conference. It also sponsored the International Screenplay Competition, with more than 1,200 entries a year. Additionally, ASA initiated the Screenwriting Hall of Fame Awards, honoring individuals who have made contributions to the art of screenwriting.
