Aubrey Plaza and Danny DeVito will soon be lending their voices to a brand new animated horror comedy coming down the pipeline at FXX.

According to Variety, actors Aubrey Plaza and Danny DeVito have both signed on to join the voice cast of Little Demon.

Described as an animated horror sitcom, the new FXX series centers on a mother who was impregnated by the Devil. 13 years later, she’s just looking to live an ordinary life out in Delaware with her antichrist daughter, but it’ll be easier said than done— especially given that Satan is very much interested in taking custody of their daughter’s soul.

Plaza and DeVito will voice the mother and Devil characters, respectively. Also joining the voice cast of Little Demon is DeVito’s own daughter, Lucy DeVito, who will be voicing the teenage antichrist.

In addition to starring in the animated horror comedy, Plaza as well as the DeVitos will serve as executive producers on the FXX original series.

Others involved behind the scenes include Darcy Fowler, Seth Kirschner, and Kiernan Valla, all of whom created and wrote the animated series, and will also executive produce.

Currently, there’s no word yet on when we might expect to see Little Demon debut, but the plan is for the series to premiere first via FXX. From there, episodes will be available to stream the next day via FX as well as Hulu.
