A month after her death, Brittany Murphy’s husband Simon Monjack has decided to file a wrongful-death action against Warner Brothers. He claims that the studio is responsible for the unexpected death of his 32-year-old wife last December.

The Daily Beast has more of the story here.

“They killed her,” he told me. Although the Los Angeles County Coroner’s Office hasn’t released a final cause of death, Monjack and Brittany’s mother, Sharon, who also spoke to me, are convinced that the once-promising star died of a heart attack from the stress caused by Warner Brother’s canceling of a contract just two weeks before she died. Murphy was excited to have begun production on the sequel to the animated hit Happy Feet, but when she was fired by Warner Brothers, Monjack says, “She was devastated.”

On top of that, a month before Warner Brothers’ decision, Brittany was fired from The Caller, and replaced with Twilight star Rachelle Lefevre. There were rumors that Monjack—who did Brittany’s hair and makeup—had been so difficult on the set, sometimes showing up drunk, that the producers had let her go.

“It’s a cruel town,” he says. “Warner Brothers relied on conjecture and hearsay about the Puerto Rico film for why they canceled Brittany’s role in Happy Feet. You’re disposable as an actress or actor.”

He’s right about that. It is a cruel town. Actors get fired all day for less things than acting flighty on set. Just ask Brit’s replacement for The Caller. Rachelle Lefevre got replaced by Bryce Dallas Howard in the Twilight saga and was heartbroken as well. It happens all the time.
