Dungeons and Dragons, the sometimes controversial role-playing game, is quite often thought to be a weird or unusual pastime that only nerds and social outcasts play. This is far from the truth, however, and here is a list of some famous celebrities who play D&D:
Vin Diesel
Ewan McGreggor
Judy Dench
Ben Affleck
Matt Damon
Kevin Smith
Daryl Hannah

All of them play or have played Dungeons and Dragons. In fact, some of them are long-time players who started in college or high school. Vin Diesel even wrote the introduction to a D&D volume.
These days, online gaming has not yet supplanted old school role-playing. Masively multiplayer online (MMO) games players may number in the tens of millions but even the best free MMORPG 2012 games would be hard-pressed to duplicate the face-to-face social dynamics of classic D&D.
