Illumination Entertainment, the studio behind the upcoming movie “Sing,” is teaming up with AMC Theaters to allow viewers to watch the animated film for free over the Thanksgiving weekend.

On Saturday, Nov. 26, at 10:00 a.m., many AMC theaters across the nation will allow fans in for free. Admission is on a first-come, first-served basis and at least 200 free tickets will be available at each theater. The tickets will be available at the box office beginning at 9:00 a.m. and doors will open at the same time. To see which theaters will be participating, head HERE.

According to Universal Pictures, the event, which is being called “Sing Saturday,” marks the “biggest advance-screening program in the history of Universal Pictures.” The film features a star-studded cast including Matthew McConaughey, Reese Witherspoon, Seth MacFarlane, Scarlett Johansson and John C. Reilly.

The film follows Buster Moon (Matthew McConaughey), a koala who runs a theater that has fallen on hard times. In order to bring the theater back to glory, Buster produces a singing competition. The movie also features more than 65 hit songs.

“We know audiences of all ages will embrace the heart and the humor of this extraordinary film and can’t wait for movielovers to experience ‘Sing’ over Thanksgiving weekend, throughout the holiday season and beyond,” said Chris Meledandri, the CEO of Illumination.

Aside from “Sing Saturday,” the studios are also holding a real-life singing contest where entrants have a chance to win a trip to Los Angeles. To enter, fans can head HERE and upload a video of them singing the Stevie Wonder and Ariana Grande song, “Faith.”
