Trailer for THE SIMPSONS Double-Sized Holiday Special "O C'Mon All Ye Faithful"

Disney+ has released a new trailer for the new holiday special from The Simpsons, titled “O C’Mon All Ye Faithful.” In the double-sized episode, famed British mentalist Derren Brown comes to Springfield and uses psychological tricks and showmanship to raise the town’s Christmas spirit.

When Homer gets hypnotized and mistakenly believes he is Santa Claus, it sets off a cheery chain-reaction and causes everyone to question what they believe and to explore the meaning of “miracle.”

Featuring musical performances by Patti Labelle and Pentatonix, this special double episode marks the 35th anniversary of the original Simpsons Christmas special, which aired in 1989.

The special will be released on Disney+ on December 17th, just in time for Christmas. Check out the trailer below, and watch the old holiday specials, available on the streamer.
