The Visual Effects Society has extended exec director Eric Roth’s contract by two years, into 2013.

Roth has been in the post since 2004. Under his stewardship, VES has doubled in size from 900 members to more than 2,200, representing more than 20 countries. During the period, VES also opened sections in San Francisco, Vancouver, London and Sydney.

“In today’s entertainment world, visual effects is at the center of the universe and VES represents the best of the best in the visual effects craft,” Roth said. “I am very pleased to have this vote of confidence from the board of VES and am proud to represent our members to the film, television, gaming and entertainment community.”

VES is “very lucky to have such a passionate, intelligent and dedicated leader at the helm,” said VES chairman Jeffrey A. Okun. “Under his leadership … VES has become the go-to source for anything visual effects.”

Up next for Roth and VES is the org’s annual VES Awards program. The Feb. 1 event will honor helmer Christopher Nolan with the inaugural VES visionary award and effects pioneer Ray Harryhausen with the VES lifetime achievement nod.
