DNegTV, the television arm of London-based visual effects house Double Negative, is set to open a facility in Los Angeles. Andy Williams, formerly head of production at Stargate Studios, has been named executive producer at the new unit.

DNegTV’s projects include NBC’s “Emerald City,” CBS’ “BrainDead,” Sky’s “Fortitude,” Marvel TV’s “Agent Carter,” and Sky/HBO’s “The Young Pope.”

DNegTV’s mission is “to work with major international broadcasters to create cutting edge VFX for high-end dramas,” said DNegTV executive producer and co-founder Louise Hussey in a statement. “Since our inception in 2013 we’ve enjoyed excellent working relationships with many of the major U.S production companies, and to ensure we can continue to offer and expand our high levels of service, it’s become key for us to have an L.A. presence.”

Williams, with over 17 years of experience in television, worked at DIVE and Alkemy X in New York before joining Stargate.

Formed in London in 1998 with a team of 30, Double Negative now also has facilities in Vancouver and Mumbai.

Double Negative picked up the best visual effects Oscar for the second consecutive year for “Ex Machina.” Earlier, the shop received Oscars for work on “Inception” and “Interstellar.” All three wins came for projects for which Double Negative was the client visual effects house working with the director and production company to lead the vfx process.
