A new Casey Anthony documentary promises to tell her side of the story

The new Casey Anthony documentary has yet to premiere, but Where the Truth Lies is already off to a controversial start. 

This true crime special revisits one of the country's most notorious cases and, for the first time, allows the defendant to speak about her 2011 trial and acquittal. 

"Casey had never given an in-depth or on-camera interview explaining her actions until now, and as a filmmaker and journalist, my interest was in getting closer to the unbiased truth by hearing all sides of the story—from opposing voices to Casey herself," director and showrunner Alexandra Dean said in a statement. 

However, will people be willing to change their opinions about the tragic story?

The three-part series will air on Peacock, which just released A Friend of the Family, a fictionalized take on the Jan Broberg kidnapper's wrongdoings. Those who tune in for Where the Truth Lies will get a never-before-seen peek at Anthony's personal archives, behind-the-scenes footage and her evidence. The limited-series is expected to cover the case, Anthony's widely scrutinized courtroom behavior and her condensed time in prison.

The teaser for the documentary leaves viewers guessing. All we hear is a narrator, likely Dean, ask "Why talk to me now when you're not getting creative control?" Before Anthony can give her answer, the clip cuts off. 

Casey Anthony trial

In 2005, Anthony gave birth to a little girl named Caylee. In 2008, shortly before her third birthday, Caylee went missing. 

Between Anthony's lies about her daughter's whereabouts, her indifference towards the child's safety and her excessive time out on the town, people grew suspicious. 

According to Biography, a forensic report detailing an examination of Casey's car is what truly up the ante of the media frenzy. The reports indicate that a hair strand from the trunk was "microscopically similar" to those found on Caylee's brush, plus a cadaver dog had identified  the odor of human decomposition in the trunk. 

Several months after searching for the toddler, her remains were discovered in a wooded area close to Anthony's home. Biography further reports that the child's skull was discovered with duct tape around the nose, mouth and jaw. 

When the case went to court in 2011, Anthony's attorneys stated that Caylee drowned in a swimming pool and the family tried to cover its tracks after the tragic accident. Despite inconsistent statements, the defendant's sources backtracking on statements and the forensic evidence, the jury found her not guilty of first-degree murder, aggravated child abuse and aggravated manslaughter of a child. However, she was found guilty of four misdemeanor counts of providing false information to law enforcement, per CNN. The verdict shocked the nation.

How to watch 'Where the Truth Lies'

Where the Truth Lies will stream on Peacock beginning November 29. 

"What emerges over the course of multiple interviews recorded over six months, is a startling psychological portrait of Casey Anthony and a complete narrative of what she says happened to her daughter weighed against multiple sources of potential evidence," Dean adds. "I believe the result will surprise many, and cause the American public to look at this story in a new light."
