While the throwback included six of the film's leads, some fans couldn't help but notice Rachel McAdams' noticeable absence.

Back in October, and more than 16 years after the film first premiered, the Mean Girls cast reunited on a special day with a special purpose.

The reunion, moderated by Katie Couric and first teased in a video from Tina Fey, encouraged fans of the film to register to vote as part of the #GoodToVote campaign.

After reaching their goal of 5,000 voter activations, Couric shared the reunion video on Oct. 3 — a day widely recognized as "Mean Girls day" based on one of the comedy film's much-quoted lines. The date also marked exactly one month before the 2020 Presidential election.
