An arts worker at London's Olympic Park says at least 2,000 performers are expected Saturday night for a secret rehearsal of the July 27 opening ceremony.
She told The Associated Press that the opening ceremony, which is being directed by Danny Boyle, will involve 10,000 performers in all.
She spoke to the AP as she escorted a lost reporter away from Olympic Stadium on Saturday afternoon and toward the Olympic Park's main press center. She spoke on condition of anonymity because she was not allowed to speak to the press.
En route, she also sharply criticized two Olympic security guards who let the reporter into the rehearsal section with no obvious credentials showing. The reporter was going in to get her media credentials validated.
