Offlot feature and TV filming in Los Angeles has remained robust in December after one of the slowest periods of 2011.

Total permitted production hit the highest level of the fourth quarter last week with 755 days — up 45 days from the previous week and nearly double the 383 in the previous frame, which included Thanksgiving.

The past two weeks are the only ones in the fourth quarter to top 700 days. The weekly average during the third quarter was around 620 days.

Last week was down 13% from the same week in 2010 when activity totaled 870 days, according to figures provided Tuesday by the FilmL.A. permitting agency.

Feature activity rose 16 days from the previous frame to 148 days, nearly triple the Nov. 21-27 figure of 58 days, which was the lowest of the year. The Barbes Brothers’ “Maniac” was the most active feature for the second week in a row with 14 permitted days.

Other films shooting in Los Angeles include “Drones,” “Chastity Bites,” “Gangster Squad,” “Isabella,” “Lust for Love” and “Seven Psychopaths.”

“Gangster Squad,” set in 1940s Los Angeles and starring Sean Penn, Josh Brolin and Ryan Gosling, has nearly completed production and is set for an Oct. 19 release by Warner Bros.

TV shooting slid 10% to 393 days compared with the same period a year ago, with “Touch” the most active production with 12 days.

Other TV productions shooting in L.A. include “90210,” “CSI,” “Southland,” “Celebrity Couples,” “Pitbulls and Parolees,” “Real Life,” “The Biggest Loser,” “The Voice,” “Top Model Sweden” and “Parks and Recreation.”

Commercial shooting shot up 41 days to 214 days compared to the previous week.
