“Once Upon A Snowman”, an all-new original short, is coming to Disney+ on October 23, and it’ll reveal the backstory of one of the most beloved snowmen in Arendelle.

Here’s how Disney+ describes the new short:

The previously untold origins of Olaf, the innocent and insightful, summer-loving snowman who melted hearts in the Academy Award®-winning 2013 Disney animated feature, Frozen, and its acclaimed 2019 sequel, are revealed in the all-new Walt Disney Animation Studios animated short, “Once Upon a Snowman”. The film follows Olaf’s first steps as he comes to life and searches for his identity in the snowy mountains outside Arendelle.

“Once Upon a Snowman” is directed by Trent Correy (animation supervisor, “Olaf” in Frozen 2) and Dan Abraham (veteran story artist who boarded Olaf’s “When I Am Older” musical sequence in Frozen 2) and produced by Nicole Hearon (associate producer “Frozen 2” and “Moana”) with Peter Del Vecho (producer, “Frozen 2,” “Frozen” and the upcoming “Raya and the Last Dragon”). Olaf is voiced by award-winning actor Josh Gad.
