Boys and girls of every age, wouldn't you like to see something strange?

DC's animated film slate for 2021 is confirmed to include a two-part adaptation of Jeph Loeb and Tim Sale's iconic limited series Batman: The Long Halloween. This revelation comes courtesy of IGN's exclusive DC FanDome panel for the upcoming animated film Superman: Man of Tomorrow.

During the panel, host Matt Bomer announced the current plans for the 2021 DC Universe Movies slate, which include two original productions, plus a two-part adaptation. The first project is the 1970s-set Batman: Soul of the Dragon, which is executive produced by Bruce Timm and stars David Giuntoli as Bruce Wayne/Batman, Michael Jai White as Ben Turner/Bronze Tiger, Mark Dacascos as Richard Dragon, Kelly Hu as Lady Shiva, James Hong as O-Sensei and Josh Keaton as Jeffrey Burr. The second film is titled Justice Society: World War II, and is due for release in spring of 2021.

Then, of course, the tw0-part adaptation is for The Long Halloween. Batman: The Long Halloween Part 1 is slated to arrive in the summer of 2021, followed by Part 2 in the fall. That being said, no casting information is available at this time. Notably, this is not the first time DC has split an animated adaptation of an iconic Batman graphic novel into two parts, having done the same thing for Batman: The Dark Knight Returns.

Written by Loeb and illustrated by Sale, The Long Halloween was first published by DC Comics in 1996. The 13-part series follows the Dark Knight as he attempts to apprehend mysterious a serial killer who murders people on holidays, once per month. In addition to the series re-introducing the villain of Calendar Man -- who knows the Holiday killer's identity, but won't tell Batman -- The Long Halloween also chronicled Harvey Dent's transformation into the villain Two-Face. Throughout the book's 13 issues, Batman also has run-ins with the likes of Catwoman, Joker, Scarecrow, Mad Hatter, Poison Ivy and the Riddler, among others.

The Long Halloween is set early in Bruce Wayne's career as Batman, taking place not long after the events of Frank Miller and David Mazzucchelli's Batman: Year One from 1987 (which got an animated film adaptation of its own in 2011). This has led to speculation that The Long Halloween at least partly serves as the inspiration for director Matt Reeves' upcoming live-action film The Batman, which takes place during Bruce Wayne's second year of crime-fighting. Rumors of a standalone animated adaptation of The Long Halloween date back to at least early 2019.
