A stuntwoman has died in a motorcycle accident while filming Deadpool 2 in the Canadian city of Vancouver.
Police confirmed the driver was killed on Monday morning and workplace safety officials were investigating.
Witnesses described how the woman lost control of the bike, jumped a kerb and crashed into a building.
The Marvel Comics sequel stars Canadian actor Ryan Reynolds and has been filming in his hometown of Vancouver, British Columbia, since June.
The Vancouver Sun reported that city centre streets had been closed since last week to film motorcycle and scooter scenes.
In a statement 20th Century Fox said: “We are deeply saddened by the accident that occurred on the set of Deadpool 2 this morning.
“Our hearts and prayers are with the family, friends and colleagues of our crew member during this difficult time.”
Local media say the stuntwoman had successfully practiced the stunt several times before the fatal accident.
The driver may have been filming a scene for the female character Domino, played by Zazie Beetz.
Photographers had spotted Beetz in costume riding a motorcycle last week.
