Mandy Moore will kick off the night with an exciting opening number, then each couple will attempt to capture the spirit of a specific movie genre. As an added bonus, Dove Cameron, Cameron Boyce, Sofia Carson and Booboo Stewart perform a “Descendants” themed medley. The couple with the highest score earned an immunity from elimination, while the rest of the couples participated in dance-offs for extra points. For each dance-off, the couple with the highest remaining score picked the opponent against whom they wanted to dance; the chosen opponent was allowed to pick the dance style (cha-cha-cha, jive or rumba). The winner of each dance-off earned two points. The general public helped to determine the winner of each dance-off via the show's official website. Judges are: Carrie Ann Inaba, Len Goodman, Mandy Moore, Bruno Tonioli.
