Spoiler Alert: This post contains details about Y2K.

Kyle Mooney is partying like its 1999 with the release of his directorial debut Y2K, a nostalgic horror comedy that plays on a familiar public hysteria 25 years later.

The Saturday Night Live alum, who directed and co-wrote the A24 film with Evan Winter, told Deadline that the coming-of-age story becomes a “whole different movie” after the unexpectedly heartfelt death scene of Julian Dennison‘s Danny.

“I felt like we knew it was coming, and it was fascinating, because we shot pretty much chronologically, and so we were making this whole different movie,” explained Mooney of the film, which is now in theaters.

Set on New Year’s Eve in 1999, Y2K follows best friends Eli (Jaeden Martell) and Danny as they ring in the new millennium at a house party, where electronics come to life after the stroke of midnight and go on a killing spree.
