A female stunt driver died on the set of the upcoming Deadpool sequel, Vancouver police confirmed Monday.

"A stunt driver has died on the set of Deadpool during a stunt on a motorcycle," read a tweet sent out on the official Vancouver police department's account.

Her name hasn't been released.

Witnesses told CTV News the stunt woman did a couple of practice runs but on the third try, she appeared to lose control of the motorcycle. She drove off set and crashed through the window of Shaw Tower across the street, narrowly missing some pedestrians.

Witness Sharmina Kermalli told the Associated Press she had just walked into a Starbucks next door to where the accident happened when she heard a loud crash. She ran out of the coffee shop and saw glass still falling on the body of the woman.

A crumpled motorcycle was seen lying on its side at the location of the accident near Vancouver's waterfront.

“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," said 20th Century Fox spokesman Dan Berger Monday in a statement.

Ryan Reynolds, who stars in the wise-cracking anti-hero franchise, announced the start of production on his Deadpool 2 June 26, writing it "feels good to be back."

Deadpool brought in $363 million at the box office when it debuted in Feb. 2016. The sequel is slated for release on June 1, 2018.

In July, a stuntman for The Walking Dead died after suffering serious injuries on the show's Georgia set. John Bernecker, 33, fell more than 20 feet onto concrete from a balcony while shooting the AMC show.

And on Sunday, a video taken on the set of Mission: Impossible 6 shows Tom Cruise limpingafter performing a stunt where he jumps between buildings. Cruise is well known for performing many of his own stunts.
