Speaking with Extra at a benefit fundrasier, Rob Lowe said the Drew Peterson story, which is set to become , is "so compelling and dark and tragic... very complex."
According to Deadline.com, the movie, will explore the two cases in which one of Peterson's wives was killed and another mysteriously disappeared.
Lowe told Extra that he's "never played anyone like Drew Peterson."
Peterson allegedly drowned his third wife, Kathleen Savio, in March 2004 but was not arrested until the disappearance of his next wife, Stacy Peterson, attracted attention to her death.
“It’s a real transformative character for me to play," Lowe told Parade Magazine. "It’s just a very different style than anything I’ve ever done before and I think people are going to be surprised.”
"It's a true story and it's kind of gnarly ... it's fun," she said in the interview. "I love "Dateline" and "48 Hours" ... so this is living out a fantasy to do one of these sorts of movies. It's going to be fun."
Lawyers for Peterson are demanding that filming for the movie be halted, arguing it invades his privacy and is nothing more than a "character assassination" that would "prejudice any potential jury pool," according to a Chicago Tribune report.
The lawyers, according to the report, ask the makers of the movie to "cease and desist" all work on the movie by Friday or face legal action.
Peterson’s latest plea to get out of jail fell on deaf ears, as an appellate court shot it down and told him he’s not going anywhere. And in July, an in the case.
Jailed since May 2009 on charges he murdered Savio, Peterson has been waiting on the appellate court to return a decision on what hearsay evidence can be used against him at trial.
The appellate court has been mulling over the matter for just shy of a year.
Lowe said the movie would likely come out in January and that they shot two different endings should Peterson's trial move forward and he be found guilty or innocent, the Parade report said.
