Sacha Baron Cohen caused the temporary shut down of production on NBC's Medium when he continued to interrupt an intense courtroom scene with Patricia Arquette.
Cohen was posing as a flamboyant fashion reporter named Bruno, collecting footage for a new follow-up film to Borat.
It wasn't until security forcibly removed Cohen from the jury box that people recognized the infamous character actor.
"No one had a clue it was Sacha playing Bruno," said a Medium insider. "It's amazing he was able to infiltrate the set and pull this off."
Shouldn't Arquette's psychic character Allison DuBois have picked up Sacha's vibe earlier?
Regular Radar readers will recall that Cohen pulled a similar stunt just before election day when he infiltrated a Prop 8 rally.
