The 1989 movie is set to be made into a TV show 20 years after it originally became an cult classic, and the programme will feature all the original characters - including Ryder's Veronica Sawyer, a popular girl who rebels against her clique of mean girls, all named Heather.
Bosses at Lakeshore Entertainment film company, who hold the rights to Heathers, have confirmed writers have begun working on scripts for a franchise after they originally debated remaking the movie.
Lakeshore President Gary Lucchesi says, "We had the title, and talked about doing a film remake at times. But doing it for TV seemed like a fresh and original idea."
Screenwriter Mark Rizzo and Sex And The City writer Jenny Bicks are set to update the dark comedy, according to Daily Variety.
