Steven Spielberg got more than he bargained for when he shouted ""action"" on a New York film set.

Just as the cameras started rolling a real life police chase crashed through the set, with police cars hurtling after a speeding driver.

The drama began minutes earlier when the driver fled from a policeman who had pulled him over.

They were going so fast you knew it wasn't part of the movie, said Rasheed Campbell, an extra in the film, Munich.

The driver was later arrested."
