People Editorial Guidelines Published on April 29, 2024 10:00AM EDT Twenty years later, Mean Girls can still sit with us. The 2004 Lindsay Lohan-starring comedy written by Tina Fey about high school hierarchies remains as timeless as ever, as a new behind-the-scenes featurette from the movie’s 20th anniversary Blu-ray edition highlights. Mean Girls “will always be timeless,” explains Ashley Park in a clip from the featurette shared exclusively with PEOPLE. The actress, who originated the role of Gretchen Wieners on Broadway, is among the cast members of 2024’s movie musical Mean Girls interviewed in the video. Park, 32, says the enduring impact behind “whatever version” of the story comes down to a simple reason: “People want to laugh.” The 10 Biggest Differences Between the New Mean Girls Movie and the Original Directed by Mark Waters, Mean Girls became a cultural phenomenon following its box office success in April 2004. Not only have Fey’s endlessly quotable lines endured in the 20 years since (even reaching President Barack Obama, who once tweeted a reference to an iconic line), the movie remains as much an educational tool for high school teachers as a cautionary tale for teenagers.

Avantika, 19, who plays the 2024 film’s Karen after Amanda Seyfried in the original film, says, “It was a huge movie for Millennials and for my generation too. It's iconic and it's such a timeless movie.” Jonathan Bennett Shares Throwback Photos with Lindsay Lohan and Lacey Chabert as Mean Girls Turns 20 “Twenty years later it’s just as poppin’ as it was when it came out,” says Renée Rapp of the original film, which starred Rachel McAdams as Regina George, queen of the popular Plastics. Rapp, 24, who also played the role in the Broadway musical, inherited the part from McAdams in the new film. “It’s just become such a cultural staple, predicting trends,” she adds — from the prevalence of pink in fashion to the notion of a tell-all Burn Book. As Bebe Wood, who followed Lacey Chabert in playing Gretchen, points out, “It really does feel like everyone kind of has their own relationship with that film.” Never miss a story — sign up for PEOPLE's free daily newsletter to stay up-to-date on the best of what PEOPLE has to offer, from juicy celebrity news to compelling human interest stories.
