Olaf's Frozen Adventure

ABC | 8:00 pm

Shown in theaters as a featurette accompanying "Coco," this animated tale continues the saga of characters from the hit 2013 Disney-Pixar movie "Frozen." Josh Gad again voices snowman Olaf, who tries to ensure that the Christmas being celebrated by Anna and Elsa (voices of fellow returnees Kristen Bell and Idina Menzel) is one that they'll never forget. Jonathan Groff ("Hamilton") also returns to the voice cast as the score boasts four original songs.
