Vin Diesel might be cool on the big screen, but in real life he's a massive geek at heart. The action star has been outed as a "huge fan" of Dungeons and Dragons.
The Hollywood icon appears opposite Rose Leslie in The Last Witch Hunter, and the actress has revealed that the 48-year-old star is an unlikely fan of the popular role-playing game.
Asked what it's like working with Vin and fellow co-star Sir Michael Caine, Rose explained: "[Vin] is such a cool guy! He's a huge fan of Dungeons and Dragons, so this movie is completely up his street.
"It wasn't intimidating. I think I was more in awe of Michael Caine, being a British actor and growing up admiring him."
However, Rose's excitement at working alongside the British legend was blunted to some extent, because in the scene she shares with the Oscar-winning star, he's pretending to be asleep.
She said: "I told my mother, 'This is so great. I get to share a scene with Michael Caine.' And then, of course, in this particular scene he is asleep. So there's no dialogue. So my mum still doesn't know that..."
Rose is best known for her starring role in the Game of Thrones series and she admits appearing on the show is a huge honour.
She shared: "I feel fortunate to have been part of it because the fan base is extraordinary and incredibly vast."
