Fox and its sibling movie studio 20th Century Fox will use Sunday’s live event to promote the feature film The Greatest Showman with a 2 1/2-minute live trailer, featuring Hugh Jackman, Zac Efron and Zendaya performing "Come Alive" from the P.T. Barnum biopic. According to Deadline, the trailer will “feature a 360-degree shoot and more than 150 dancers and that filming will take place adjacent to the A Christmas Story Live! stages at the Warner Bros Studios in Burbank.” Fox also announced that A Christmas Story Live! will open with the original song “Count on Christmas,” written by the show's composers, Benj Pasek and Justin Paul (the musical duo behind La La Land and Dear Evan Hansen).
