ABC Family is developing a made-for-tv movie based on the real-life discrimination faced by lesbian teen Constance McMillen.

McMillen, with the assistance of the American Civil Liberties Union (ACLU), sued her rural Mississippi school district in March after it decided to cancel the annual prom dance for junior and senior students rather than allow McMillen to attend the event with her girlfriend and wear a tuxedo.

School officials in July agreed to pay the teen $35,000 in damages plus attorneys fees and adopt a policy prohibiting discrimination. Officials, however, did not admit to any wrongdoing in their offer.

The case drew nationwide attention, turning the teen into an overnight gay rights celebrity. She served as a grand marshal for New York's Gay Pride Parade.

According to Nikki Finke's Deadline Hollywood, ABC Family is in the early stages of developing the film. The movie is being helmed by openly gay producers Craig Zadan and Neil Meron. John Gray, creator-executive producer of CBS' Ghost Whisperer, will write the script and is expected to direct.

Previous gay-related productions by the Zadan-Meron team include GLAAD Media Award-winners Serving in Silence: The Margarethe Cammermeyer Story and What Makes A Family.
