Back in August, Warner Bros., Hasbro and Sweetpea Entertainment finally resolved a long-running legal battle swirling around the rights to Dungeons & Dragons, announcing that a live-action theatrical movie is finally moving forward. We haven't heard much about the project since then, but today The Tracking Board reports that the project has brought on Goosebumps director Rob Letterman to take the helm. The filmmaker will be working from a script by David Leslie Johnson (Wrath of the Titans), who was attached when the project was announced last year.

Dungeons & Dragons was created by E. Gary Gygax and Dave Arneson in 1974 as a fantasy roleplaying game and since then has amassed millions of players and fans worldwide. The hugely popular property has also influenced numerous writers, directors, game designers, and other creative professionals throughout its four decades. The game previously spawned the 2000 adaptation Dungeons & Dragons, which famously flopped at the box office, earning just $33.8 million worldwide from a $45 million budget.

The Tracking Board reports that the adaptation will center on a warrior and a group of creatures who embark on a perilous journey to find a legendary treasure. Some of the creatures joining this warrior include a "half-dragon" and a "cunning gnome." It isn't known if any of these roles will be based on specific characters from the original game.

Back in September, Vin Diesel, a longtime D&D player, claimed that the game's late creator E. Gary Gygax wanted the actor to "tell his story," shortly before he died in 2013. It isn't known if this means E. Gary Gygax wanted Vin Diesel involved in a biopic of some sort, but there are reports that the producers want a "Vin Diesel-type" for the lead character. No cast members have been attached at this time, but now that a director has come aboard, we may hear about casting in the near future.

Hasbro's Brian Goldner and Stephen Davis are producing with Courtney Solomon of Sweetpea Entertainment and Vertigo Entertainment's Roy Lee and Stephen Davis. Allan Zeman will executive producer for Sweetpea, with John Powers Middleton executive producing for Vertigo. Rob Letterman most recently directed Goosebumps, and his other credits include Shark Tale, Monsters Vs. Aliens and Gulliver's Travels.
