Sandra Bullock's husband Jesse James was almost killed by a crazed stalker.The actress watched in horror as Marcia Valentine repeatedly tried to run James over outside the couple's Orange County home at the weekend.Valentine - who police say has stalked Sandra in the past - laid in their driveway and when James came out to inspect she jumped in her car and attempted to drive over him three times. Orange County Sheriff's spokesman Jim Amormino said: "On several occasions before this incident Sandra Bullock and Jesse James found Marcia Valentine lying in front of their garage door. On the morning of Sunday, April 22 around 10.30 am, James went out and asked her to leave."She yelled some obscenities at James and went to her car and threw the car in reverse in his direction. He attempted to move out of the way and she kept moving the vehicle. She attempted to run him over three or four times. She then drove off on Pacific Coast Highway. James called police and told them he did not know this woman. He then gave them a detailed description of her to the police - she drove a silver Mercedes with a white decal on the rear. He described her as a 5ft 4in white female. "James escaped the frenzied automobile attack without injury.Valentine, who fled the scene, was picked up by police the following day. James positively identified her in a police line-up.The case has been sent to the Orange County District Attorney's office and Valentine faces charges of assault with a deadly weapon. Her bail was set at $25,000 and she is due in court on May 22. Sandra's representative Cheryl Maisel said: "Both Jesse James and Sandra Bullock are fine and it is now in the hands of the authorities."
