Every year fans flock to San Diego, California for the mecca of geek gasms: Comic-Con. Being an entrepreneurial opportunist and perhaps nerd-genius, spring-boarding off that worldwide phenomenon, star Zac Levi took his popularity and passion and channeled it into a convention that has paralleled Comic-Con for the past two years.

Creating his brainchild The Nerd Machine with the help of some like-minded celebs, friends and anyone with a kindred spirit, Zac created a world for nerds, geeks and fans to mingle and celebrate. In fact, Zac found a way to bringing all these fantastic worlds together for a special 4-day event known as Nerd HQ. This year, with over 18 “Conversations for a Cause” panels featuring the talents of such popculture stars as Joss Whedon, Stan Lee, Nathan Fillion, Damon Lindelof, and Jared Padalecki as well as featuring hot shows like DOCTOR WHO, CHUCK, PSYCH and GRIMM and film casts from EXPENDABLES 2 and TWILIGHT: BREAKING DAWN, the Nerd HQ event managed to showcase some of the year’s hottest celebs.
