TV pilots have been driving Hollywood location shooting, led by police procedural “Gang Related,” with 60 permitted days.

Gang Related,” from Imagine Entertainment in association with Twentieth Century Fox TV, was by far the most active shoot last week, according to figures released Tuesday by permitting agency FilmL.A.

Fox ordered the pilot in January. In the project, a gang member sent to infiltrate the San Francisco Police Department battles conflicting loyalties to the two camps. Chris Morgan (pictured above) is exec producing “Gang” with Brian Grazer, Francie Calfo and Scott Rosenbaum.

Another pilot, NBC Universal’s “Blood Line,” generated 21 days of permitted shoots last week.

TV shoots totalled 408 days, up 12% from the same week a year ago. Feature activity lagged with just 40 days, led by seven for “Punjabi Professional” and five days each for “The Townies,” “La Guapa” and “April Rain.”

Commercial shoots totaled a robust 186 days last week, up 13 days from the year-ago period.
