There’s a stickiness to “Mean Girls” quotes. For a certain generation, long passages can be plucked from the mind and performed, cadence-perfect, on demand. As a child, I watched the movie over and over on DVD, and the words wormed their way into my impressionable mind.

My experience is by no means unique. “It became part of my vernacular,” Samantha Jayne told The Times of her teenage reaction to the film, which was released in 2004. “Every single sound bite.”

Jayne is a co-director of a new version of “Mean Girls,” which came out on Friday. It’s an adaptation of an adaptation, refashioning songs from the 2018 Broadway musical based on the movie. (It should also be mentioned that the original film was inspired by a nonfiction book.)

Like its predecessor, the new “Mean Girls” follows Cady Heron (Angourie Rice), a teenager who has arrived at an American high school after being home-schooled by her zoologist parents in Kenya. She is introduced to the terrors of a teenage social hierarchy and drawn into the orbit of a group of popular girls, led by Regina George (Reneé Rapp).

Along with adding musical numbers, the filmmakers updated the script to better reflect our times. Some dated and less-sensitive jokes have been retooled. And there’s greater diversity: Karen Smith, played in the original by Amanda Seyfried, is now Karen Shetty, played by the Indian American actress Avantika.

In the nearly 20 years since its release, “Mean Girls” has remained unshakably relevant. “It has this little net that catches girls as they pass through preteen and high school age,” Tina Fey, who wrote both the original film and the reboot, said in 2014.
