We had heard rumors that this might be in development, and Deadline has now confirmed that a live-action adaptation of 2017 animated short Dear Satan is in the works from the directing/producing team of Bobby and Peter Farrelly.
Jack Black, who worked with the brothers on Shallow Hal, is on board to play the Devil, alongside a supporting cast consisting of Robert Timothy Smith, Keegan-Michael Key, Brianne Howey, Hayes MacArthur, PJ Byrne, Jaden Carson Baker, Kai Cech and Austin Post.
The story focuses on a young boy, who in writing his yearly note to Santa, mixes up the letters and sends it to the man downstairs instead. Delighted to have a fan, Lucifer arrives at the kid's doorstep.
Though the project is clearly based on Dear Satan, it looks like the studio might go with the more marketable and family-friendly title Dear Santa (unless Deadline got their wires crossed here).
You can check out the original short below.
No production start date has been announced, but Black did take to Instagram to share the following pics.
