WHAT happened to Olaf in between his creation during Elsa’s “Let It Go” moment and his “warm hugs” introduction to Anna and Kristoff in the first “Frozen?” These “untold origins” will now be the subject of a new animated short film coming to the Disney+ streaming platform this October.

Josh Gad will return to voice the snowman in “Once Upon a Snowman,” which is directed by Trent Correy and Dan Abraham. Correy was the animation supervisor for Olaf on “Frozen 2” and he appeared in the making-of “Frozen 2” docuseries “Into the Unknown” on Disney+. Abraham storyboarded Olaf’s “When I Am Older” musical sequence in “Frozen 2” and he directed an episode of the previous Olaf short series “At Home With Olaf.”

“Once Upon a Snowman” will be released Oct. 23 and follow “Olaf’s first steps as he comes to life and searches for his identity in the snowy mountains outside Arendelle,” according to a press release.

Disney+ found success with “At Home With Olaf,” which Hyrum Osmond, the supervising Olaf animator on the first “Frozen,” developed partly in quarantine for an online release. (SD-Agencies)
