6. Vin Diesel – Dungeons & Dragons
Vin Diesel has apparently been playing Dungeons and Dragons since the 1970s, proving that this action star is really just a closet nerd. He still plays today, and apparently shows off his love for the game with a tattoo of his character’s name “Melkor” on his stomach. He was even chosen to write the forward for 30 Years of Adventure: A Celebration of Dungeons and Dragons.
