Durst was later suspected of murdering one of his neighbours and Kathy's family feared he might have been involved in his wife's disappearance. The Spiderman actress undertook months of research before tackling the role, even having dinner with Kathy's relatives and talking to them about the case.
"There was a documentary plus much research to understand these people. I spent time with her family, had dinner at their house, listened to them, got their blessings for this film," the Daily Star quoted her as telling the New York Post.
"Nervous at first that this ugly story's coming back to public life, they had kind words for me but were emotional. It was almost cathartic for Kathy's brother," she added.
