The Facebook AR filter will celebrate the on-screen transformation of Twelfth Doctor Peter Capaldi into Thirteenth Doctor Jodie Whittaker.

GLOBAL–BBC Worldwide Americas has launched a new augmented reality filter for the Facebook Camera Effects platform to coincide with the Christmas special “Doctor Who: Twice Upon a Time.”

The effect invites users around the world to undergo the “regeneration process” for the first time. “Doctor Who” fans can experience the “golden glow” and shapeshifting process that allows an alien Time Lord to change into a new body thanks to AR technology.

In addition, the Facebook Camera Effects feature will celebrate the on-screen metamorphosis of Twelfth Doctor Peter Capaldi into Thirteenth Doctor Jodie Whittaker during the 2017 Christmas special.

“Doctor Who: Twice Upon a Time” will premiere on BBC America in the U.S. and Space in Canada on Dec. 25, and will be available in theaters nationwide for one night only on Dec. 27 through a partnership with Fathom Events.
