To promote his new film The Last Witch Hunter, action star Vin Diesel sat down with Nerdist and Geek & Sundry to play a game of Dungeons & Dragons. It wasn't his first time, as he told his followers on Facebook in a behind-the-scenes video two weeks ago.

In an interview with HitFix, Diesel revealed that were it not for D&D, The Last Witch Hunter wouldn't exist. "For the 30th anniversary [of] Dungeons & Dragons, the company at the time asked me to write the foreword for [Thirty Years of Adventure: A Celebration of Dungeons & Dragons]," he said. "I talked about my experience growing up playing Dungeons and Dragons religiously. I even talked about a character that I had named Melkor—a name that obviously I stole from The Silmarillion—and that character was a witch hunter." Because the personality Diesel created inspired The Last Witch Hunter, it made sense for Nerdist and Geek & Sundry to organize the game.

Playing as his character from the film, Kaulder the Witch Hunter, Diesel gets way into the game and manages to help his team make it through the 30-minute adventure. Watch the highlight clip above, or you can click through to see the longer version here.
