A stuntwoman has died in a horrific motorcycle crash on the set of the new Deadpool 2 movie filming in Vancouver.
The rider successfully completed the stunt four times in the Canadian city's Jack Poole Plaza, before disaster stuck on the fifth attempt.
Local media reports the "the throttle somehow engaged" and the rider lost control while 'stood' on the motorbike.
Witnesses said the bike flew through the air and crashed though glass window on the ground floor of the Shaw Tower.
Onlookers thought the crash was part of filming but quickly realised it was a serious "unplanned" crash, they told TV crews.
There was said to be no sound of brakes before the crash.
In a 911 call to emergency services, the tragedy initially described as "an actor on a stunt set who has gone through a window".
An unidentified male caller says: "The actor lost control, went across the street, over a curb and through a glass pane window into a building across the street."
The emergency services call handler says: "The actor went through the window of vehicle, or something?
A male caller says: "No, the actor lost control, went across the street, over a curb and through a glass pane window into a building across the street."
Another voice says: "Just so that guy is aware, the stunt actor was airborne through the building."
A voice sounds as though they describe the actor as "hasn't been moving".
