Offlot feature and TV filming has moved into the deep freeze in Los Angeles as is typical late in the year, with total permitted production last week sliding 42% below the previous week — and feature filming at its lowest point of the year.

Production days totalled 383, down 281 days from the prior frame. Last week’s total was up 6% or 21 days from the same frame of 2010 in what’s the usual pattern as the year draws to a close.

“Production tends to slow down after the Thanksgiving holiday and through to the end of the year,” noted FilmL.A. spokesman Philip Sokoloski.

Feature activity totalled 58 days, up 22 days from the 2010 frame — but seven days behind the first week of November 2011, which had been the lowest total of the year. The 2011 highs came in June with 246 days and 229 days during the last two weeks of that month.

Olivia Entertainment’s “The Trace” was the most active feature with 12 permitted days, according to figures provided Tuesday by the FilmL.A. permitting agency. Other films shooting in Los Angeles include “Magnus Rex,” the production name for Warner Bros.’ “The Dark Knight Rises” and an untitled Kevin Harding project — each with seven days — along with “A White Trash Christmas” and “Oblivion.”

TV shooting declined 7% to 280 days, with “Jimmy Kimmel Live” the most active single production with 28 days. Other TV productions currently shooting in L.A. include “True Blood,” “Southland” and “Braxton Family Values.”

Commercial shooting shot up 80% to 45 days with a GDF spot racking up the most days at 14, followed by an Audi E-tron spot with eight.
