Location filming in Los Angeles surged to its highest level of the year last week, thanks to major gains in TV and spots.Offlot shoots hit 1,030 days, up 36% or 275 days over the same frame in 2012. It’s the first time in 2012 that the total has topped 1,000, according to figures disclosed Tuesday by the FilmL.A. permitting agency. Commercials posted the biggest jump with a 53% hike with the most active shoots for Firestone, GMC and the NBA. Production in Los Angeles has been on an upward trajectory throughout the fourth quarter with double-digit gains in most weeks. “The gain in spots is a sign that the economy is improving but we’re not really sure what’s driving the gains in film and TV,” noted FilmL.A. president Paul Audley. Feature activity was led by Alcon’s Hilary Swank drama “You’re Not You” with a dozen days and by Gregg Araki’s “White Bird in a Blizzard.” Indie sci-fi thriller “Stranglehold” wrapped with shots in the LA Metro Rail subway, Gower St., Avalon Blvd., Beverly Hills and the beach at Topanga. The mainstay TV category posted one of its most active weeks of the year with sitcoms “Raising Hope” and “The Next” the most active. The Union Rescue Mission, a charity serving the homeless, has announced that it’s teaming with location agency Real to Reel Locations to reach out to productions to shoot at the mission’s facilities in downtown L.A. and its Hope Gardens Family Center. All revenue generated from filming will go directly back into the mission’s programs. Comedy Central’s “Workaholics” and ABC’s “Criminal Minds” have shot at mission locations.
