The husband of cinematographer Halyna Hutchins has filed a wrongful death lawsuit against Alec Baldwin and others on the set of the movie Rust.
Hutchins, 42, was shot dead in October last year while filming the western in New Mexico.
The lawsuit was expected, but a lawyer for the family has now confirmed that papers have been filed in the state’s Santa Fe county.
The couple’s nine-year-old son is also named as one of the parties in the case, said lawyer Brian Panish.
He said Baldwin “and others responsible for safety on the set” were the target of the lawsuit.
The “reckless conduct and cost-cutting measures” of the actor and producers “led to the death of Halyna Hutchins”, said Mr Panish.

Hutchins was killed and director Joel Souza injured when a prop gun being used by Baldwin during a rehearsal on 21 October fired a real bullet.
No criminal charges have yet been brought and the incident is still being investigated.
Baldwin, 63, has previously said he was told the gun was “cold” – meaning it was safe to handle, and that it went off without him pulling the trigger.
At least three other cases have been filed over the shooting but this is the first directly related to one of the people shot.
