Hollywood remains effectively at a standstill as twin writer and actor strikes show no sign of ending. The WGA and SAG-AFTRA filed a complaint with the National Labor Relations Board this week against Comcast’s NBCUniversal, which the unions say blocked a sidewalk picketing area, forcing strikers to walk on busy roads. Meanwhile, L.A. City Controller Kenneth Mejia said the city did not issue any trimming permits for the shade-providing trees outside Universal Studios, which were trimmed down where union members are picketing amid a persistent heat wave.
