The 1988 movie Heathers was basically the original Mean Girls. Winona Ryder, Shannen Doherty, Lisanne Falk, and Kim Walker played a clique of high school girls who were the epitome of terrifying teens. Ryder's character, Veronica, misses her old friends and hates that she's part of the Heathers. Her psychotic boyfriend J.D., played by Christian Slater, goes around killing all the people he doesn't like, which includes the Heathers. Ah, to be young again!
The movie is a cult classic, and gave us iconic lines like "What's your damage?" and "f--k me gently with a chainsaw..." But people were less than impressed when not only was it revealed that Heathers was going to be remade, but that now it was going to be a TV show instead of a movie.
Selma Blair signed on for a recurring role in the series, and Shannen Doherty was slated for a guest appearance as well. Those were the only real similarities between the original and the series, though. Heather Chandler is all about promoting body-positivity as a social media influencer, Heather McNamara is a lesbian, and Heather Duke is portrayed as genderqueer. It got a lot of people wondering why even bother claiming it to be a remake if you're changing so many aspects.
The show was set to premiere on March 7th, but one big social movement prompted the studio to push it back.
