Elizabeth Banks starrer “Walk of Shame” has provided a boost to Los Angeles film production at a time when shooting tends to be fairly sluggish.The Lakeshore-Sidney Kimmel comedy, due to wrap Wednesday, has been shooting in a variety of locations recently including Saturday and Sunday mornings on a closed-down portion of the 710 Freeway in Alhambra; the Classic Club Service tow yard and a house on Orion Avenue in Van Nuys; the Cal State campus in East Los Angeles, which included a helicopter landing; the Malabar Public Library; and KCET-TV in Burbank. Earlier shooting took place on locations including the My Studio nightclub on Hollywood Boulevard, a loft on Traction Avenue in the Arts District, an alley behind the Orpheum Theater, an office building on Spring Street and a Sun Chemical warehouse on Santa Fe Avenue. Banks is portraying a high-strung news anchor who, after a wild night out, finds herself locked out on the street with no phone, money, ID or car and embarks on a series of misadventures on her way to an important job interview. “Walk of Shame,” which also stars James Marsden and Gillian Jacobs, is directed by Steven Brill from his own script. Lensing began Dec. 19, followed by a holiday hiatus and six weeks of shooting. “Walk of Shame” led location activity in mid-January with 17 permitted days and logged 14 days more last week, second to “The Paper Boat” with 21 days, according to figures released Tuesday by the FilmL.A. permitting agency. “Max Rose,” the first film from Jerry Lewis in more than a decade, logged 10. Overall location shooting has remained relatively robust in recent weeks. The mainstay TV category was led by “Southland” with 30 days and sitcom “Awkward” with 17.
