Emma Watson left shaken after fan run-in

EMMA WATSON was left shaken after an overzealous fan broke through security on the set of her new film NOAH in a bid to hand her a letter, according to a U.K. report.

The British actress is currently working on the biblical epic with Russell Crowe in Long Island, New York, and was filming in a wooded area when she spotted the man.

Security guards and stunt artists working on the film then chased the intruder and restrained him until police arrived.

A source tells Britain's The Sun, "The man managed to slip on to the set with some visitors and then approached her... He took off into the woods and was chased by security and a couple of the tough stunt guys who also happen to be martial arts fighters.

"They caught up with him in the woods. Police were called and he was removed by security."

The publication reports the man was not arrested but was handed a warning about trespassing.
