The final week of 2012 racked up the slowest activity level of the year in location shooting in Los Angeles as show business closed up shop for the holidays.Offlot shoots totalled 128 days, according to figures disclosed by the FilmL.A. permitting agency, or six more days than the same frame in 2011. The week is typically slow — and represented a decline of 902 days from the first week of December, the highest level of 2012. Reality TV shows “Push Girls: Season 2″ and “Top Model Sweden” racked up the most activity with 21 and 15 days respectively. Feature filming activity was microscopic with nine days, including seven for “OT Beach.” The Los Angeles region’s location activity had been well above average with double-digit gains during many weeks of the fourth quarter. Alcon’s “You’re Not You,” starring Hilary Swank, and Lakeshore/Sidney Kimmels’ “Walk of Shame,” starring Elizabeth Banks, were the most notable movies shot locally during December. FilmL.A. reported this week that Griffith Park was the most active site for location filming in 2012 with 409 days, followed by Point Dume State Beach with 163 days.
