The project has actually been in development for some time. The studio is re-working David Johnson's script Chainmail, which was based on a more obscure game created by E. Gary Gygax before Dungeons & Dragons, to fit the Dungeons & Dragons world. No story details were given.
Roy Lee is producing, with Alan Zenman executive producing. Courtney Solomon, who directed the 2000 feature Dungeons & Dragons, is also attached as a producer. The game was previously adapted into the 1983 animated TV series Dungeons & Dragons.
David Johnson's other writing credits include Red Riding Hood, Orphan, and two episodes of The Walking Dead.
