Nerdin' Out.

A Tour of Last Weekend's Sci-Fi Expo.

Last weekend, the folks behind the Dallas Comic-Con took over the Irving Convention Center for their other big ticket annual event, the Dallas Sci-Fi Expo, which featured appearances from the casts of Back to the Future, Battlestar Galactica and The Walking Dead.

Also present? Tons of cosplaying fans. Tons of them.

Fans of all things nerdy ourselves, we decided to take in the whole experience, too — and document our findings on film. Check out the fruits of our labor below.
