June 6, 2014— -- intro: Theater audiences beware. If you behave badly -- forget to turn off your cellphone before the performance or try to sneak a pic of your favorite star on stage -- you risk a scolding from none other than the stars themselves.
That's exactly what happened when a cellphone interrupted Oscar-winning actor Kevin Spacey midway through a powerful speech during his one man-show, "Clarence Darrow," at London's Old Vic theater.
When the guilty party failed to silence the phone quickly Wednesday, the Independent newspaper reported, Spacey -- still in character -- finally snapped, "If you don't answer that, I will.”
The 54-year-old actor's unscripted response earned him a rousing applause from the audience.

According to Playbill.com, the actor tweeted during intermission, "Dear person taking pictures during our show tonight..the ushers are going to be looking for you and you will be thrown out. You are insanely distracting to all of the actors onstage and incredibly rude. If you read this, please leave and don't come back. I'm happy to take pics outside after the show... please be respectful."

quicklist:title: Helen Mirrentext: It wasn't the audience but a bunch of noisy drummers outside the theater that proved a distraction while Helen Mirren was performing in "The Audience" in London's West End last year. Still dressed in character as Queen Elizabeth, the actress waited until intermission to exit the stage door and give the drummers, promoting a festival for gay and transgender people, a royal lashing.
"I'm afraid there were a few 'thespian' words used. They got a very stern royal ticking off but I have to say they were very sweet and they stopped immediately," Mirren told the Telegraph. "I felt rotten but on the other hand they were destroying our performance so something had to be done." media: 24030790
