Two local actors -- a brother and sister -- were the ones caught up in a bizarre, straight-out-of-the-movies carjacking in downtown Vancouver Tuesday, a source close to the family told CTV News.

According to the source, Kris and Carly Pope were in their BMW when a man who they did not know suddenly jumped on the hood of their car while the car was stopped.

Kris Pope got out of the car, at which point the stranger jumped into the driver's seat and put it in reverse, the source said.

Kevin Bow told CTV News he watched from the balcony of the nearby Sandman Hotel as the BMW's driver and a Samaritan attempted to wrestle the suspect out of the car.

"They tried pulling him out," Bow said. "He hammered it in reverse, the two guys kind of fell out and went flying halfway across the intersection."

"After they hit the ground then they started yelling for help."

Vancouver police Const. Anne Longley said the suspect then backed up quickly into oncoming traffic, hitting three other cars before crashing into the glass window of the CBC building located at the corner of Georgia and Hamilton streets.

Witnesses told CTV News a woman was in the backseat while the car was going in reverse.

The Pope family source said Kris Pope was released from the hospital Tuesday night, but Carly Pope remained in the hospital.

The suspect was arrested at the scene before being taken to hospital for treatment of head injuries, police said.
