Production on Patricia Arquette's hit US TV drama Medium came to a halt earlier this month when comic Sacha Baron Cohen invaded the set as his fashion reporter creation Bruno.
Filming was temporarily shut down as the Borat creator, posing as an extra, was forcibly removed from the set after interrupting a tense courtroom scene.
An insider for the show told EW.com, "No one had a clue it was Sacha playing Bruno. It's amazing he was able to infiltrate the set and pull this off."
It's not the first time Cohen has hit the headlines for his crazy antics this year - he has been disrupting fashion shows, political rallies and launches all over the globe, filming guerrilla segments for his new film 'Bruno: Delicious Journeys Through America for the Purpose of Making Heterosexual Males Visibly Uncomfortable in the Presence of a Gay Foreigner in a Mesh T-Shirt'.
