Amber Heard facing lawsuit over London Fields movie

Actress Amber Heard is facing a lawsuit over her troubled movie London Fields.

The Magic Mike XXL star teamed up with her ex-husband Johnny Depp onscreen last year (15) for the movie, in which Amber played a femme fatale opposite Billy Bob Thornton.

The thriller, based on the 1989 book of the same name by Martin Amis, had been due to premiere at the Toronto International Film Festival in Canada last September (15), but it was pulled from the schedule after director Matthew Cullen filed a $1 million lawsuit against the movie's producers, accusing them of using "fraudulent efforts" to rework the movie without his knowledge.

Now Heard is facing a lawsuit from the producers for breach of contract and committing tortious interference, according to The Hollywood Reporter.

"While the inherent tension between actors and directors (on the one hand) and producers (on the other) is nothing new in Hollywood, the unauthorized and unlawful acts of Heard, Cullen, and others - most notably, their campaign to damage Plaintiff, the Picture, and the Picture's investors - are perhaps unprecedented," the complaint filed in Los Angeles Superior Court reads. "Indeed, as a result of their misconduct, which continues to this day, the very promising Picture remains in limbo, hijacked and placed under a cloud by Heard, Cullen, and others."

In the complaint, Heard is accused of refusing to attend promotional appearances including the TIFF premiere. She is also facing accusations of conspiring with Cullen to violate his contractual agreements.

The film's producers are seeking at least $10 million in compensatory damages.

The lawsuit news comes months after Heard settled her contentious divorce with Depp in August (16).
