The widow of Kill Bill actor David Carradine is seeking damages from the French film company behind his last movie, saying it failed to protect him.
Carradine, 72, was found in a Bangkok hotel room last June, while filming Stretch, having died from asphyxiation.
In legal papers, Anne Carradine says an assistant employed to help him around the city went for dinner without him because he was not in his hotel room.
A representative for the company, MS2 SA, was not available for comment.
Mrs Carradine claims in the papers, filed in Los Angeles, that the assistant and other members of the film crew left for dinner without her husband, who she says had been in the city for three days.
She says he called the assistant an hour later but was told the group were on the other side of Bangkok and that he should make his own arrangements for the evening.
"Defendants were negligent in failing to follow industry standard and provide David Carradine, the performer, with sufficient assistance during the course of filming Stretch in Bangkok, Thailand," the court documents say.
In the papers, Mrs Carradine also said she was having difficulty collecting money from the company's insurance policy for the actor.
Carradine was found naked in a wardrobe with a cord around his neck and other parts of his body on 4 June last year.
The doctor who oversaw a private post-mortem examination concluded that the actor had not killed himself.
"He didn't die of natural causes and he didn't die of suicidal causes," forensic pathologist Dr Michael Baden said.
"That leaves some kind of accidental death."
