A female stunt driver was killed on a motorcycle on the set of Deadpool 2 today in Vancouver. The woman, who was reportedly an “experienced road race racer” but was doing her first film as a stunt performer, was not wearing a helmet during the stunt, according to Deadline.

The incident marks the second time a stunt person has died on set in the several months. Last month stuntman John Bernecker died on the set of the Walking Dead, which was widely reported as being the first stunt-related death in 17 years. The same month a jury also awarded $11.2 million to the family of Sarah Jones, a camera assistant who died in a train crash while working on the movie Midnight Rider in 2014.

Even though the stuntwoman on Deadpool 2 rehearsed the stunt many times, all weekend crew members are quoted by Deadline as feeling overworked due to 16-hour days on set. The victim has still not been identified.
