Off-lot production in Los Angeles surged 8% last week as feature filming posted its most active period of the year.

Large scale productions gearing up included “Pirates of the Caribbean: On Stranger Tides” and “The Girl With the Dragon Tattoo,” which pulled their first permits for offlot shooting last week.

Production totaled 696 permitted days during the week that ended Sunday, compared with 644 the same tine last year, according to figures released Tuesday by the FilmL.A. permitting agency.

Feature activity shot up 79% to 122 days as an untitled comedy by production company Derf II posted the highest number of permitted days at 26, followed by “Welcome to People” with 18 and “Monster Slayer” at 12. Other pics included “The Lid,” “Default,” “Tim and Eric’s Billion Dollar Movie” and “Stitch.”

Feature shoots during 2010 were up 8.1% on 2009 to 5,378 days, or a weekly average of 103 days. Offlot feature shooting still remains far below the levels of the mid-1990s.

TV shoots for the week fell 16% to 366 days, 68 fewer than the same week last year. NBC Universal was the most active offlot producer with 47 days, led by 26 days for “The Office.” FilmL.A. spokesman Todd Lindgren said the agency is tracking nearly identically to last year in terms of the number of unique titles pulling TV pilot permits. Pilots shooting this week include “Grace,” “Damage Control,” “Autumn Harvest” and “Man Up.”

Commercials posted a 46% hike during the week with 208 days. Prettybird Pictures was the most active with 23 days, including 16 for an Axe spot.
