Work at Ryan Murphy‘s production company was disrupted for a couple of hours today. When an office assistant was opening a letter from a fan who wanted Murphy to read his script, a little bit of white powder spilled out. As a precaution, the Paramount-based production offices were evacuated and a HazMat team was called in. According to LAPD spokeswoman Karen Rayner, after a brief investigation, the police determined the substance was not hazardous. Everybody at the offices, which house Murphy’s three shows under his 20th Century Fox TV deal — Glee, American Horror Story and The New Normal — are now back at work.
