The creators of Aussie film Fatal Honeymoon have promised to delve "deep" into the psychology of Gabe Watson, who pleaded guilty to the manslaughter of his wife, Tina Watson.
Hollywood heavyweight Harvey Keitel will play Tina's father, Tommy Thomas, whose determined pursuit of justice will be a focus of the movie, producer David Parker says.
Melbourne actress Amber Clayton will play Alabama college graduate Tina Watson, whose "loving relationship" with her father is also explored in the film.
Clayton said Keitel, known for his tough-guy parts such as in Martin Scorsese's Mean Streets, "is much softer" in this role.
"He plays a beautiful southern gentleman ... Tina's relationship with her dad is heartbreaking," Clayton said.
Harvey was phenomenal to work with. He wanted to get to the bottom of the scenes. He did as much research as he could."
Watson's wife died on a Whitsundays seabed while on their honeymoon dive in 2003. Watson, 35, served 18 months in prison before his release in November 2010.
His eight-day "murder for money" trial in Alabama was dismissed this February for lack of evidence.
Parker and his director wife, Nadia Tass, a long-time film-making couple with hits such as Malcolm and The Big Steal, said the movie would have an ambiguous ending.
"We are presenting both points of view," Parker said. "We are very respectful. You are dealing with people who are still alive."
The film, to be released in Australia next year, is being shot on the Gold Coast.
