VANCOUVER, British Columbia

“Deadpool 2” star Ryan Reynolds is mourning the death of a motorcycle stunt driver killed during production Monday.

Reynolds released a statement on Twitter a few hours after the accident near the waterfront in downtown Vancouver.

“Today, we tragically lost a member of our crew while filming Deadpool,” the actor wrote. “We’re heartbroken, shocked and devastated … but recognize nothing can compare to the grief and inexplicable pain her family and loved ones must feel in this moment.”

Reynolds, a native of Vancouver playing the Marvel Comics superhero Deadpool in the 20th Century Fox movie, said his heart “pours out to them.”

The motorcycle crash happened near the Shaw Tower office building, where a crumpled motorcycle was seen lying on its side and a window was smashed.

Nathan Kramchynski, who works on the seventh floor of the building, said he watched rehearsals for the stunt outside the Vancouver Convention Centre. The stunt woman had been riding the motorcycle down a set of stairs from the center and had stopped when she reached the street, he said.

But on the occasion when the accident happened, the driver appeared to pick up speed, crossed the street and swerved to avoid pedestrians before disappearing from his view, Kramchynski said.
