The makers of new documentary Amanda Knox made a promise not to play judge and jury.

While the Ramsey family threatened to sue after The Case of JonBenet Ramsey doco pointed the finger firmly at younger brother Burke Ramsey, Amanda Knox filmmakers Rod Blackhurst and Brian McGinn said they haven't made a "whodunit" about the tragic murder of Brit Meredith Kercher in Italy in 2007.

Instead, they were on a quest to discover why the case still fascinates the public close to a decade later.

In the process, the duo uncovered unseen footage of Kercher taken from Knox's phone in the weeks prior to the murder plus tapped phone conversations between Knox and a friend.


The call, made in the days after the murder, reveals Knox alternated between bragging about her boyfriend being "super hot" and being incredibly nervous in the police station and wanting to "bust in to crying".

In addition, they uncovered there had been a continuing relationship between Knox and her co-accused, Raffaele Sollecito, with Knox filmed sharing her joy over the phone with Sollecito after their final exoneration in 2015, eight years after the they were first arrested.

Sollecito also revealed he attempted to send Knox flowers when they were initially convicted.

"I wanted to send her flowers for her birthday," he told the documentary makers.

"Even though I'd only known her five days (prior to the murder), those five days were everything."

The documentary also re-airs disturbing footage from the blood-soaked murder scene. It has found footage of Knox and Sollecito kissing and cuddling outside the crime scene which, at the time, was seen as evidence of their guilt. Seen from a different wide angle, it gave the filmmakers pause.

"In the wide shot you see the whole scene ... and the situation is so chaotic that it calls into question, 'Was their behaviour in appropriate or were they simply consoling each other?'" said McGinn.

Knox - or "Foxy Knoxy" as she was anointed by the press at the time - along with her boyfriend of a week, Sollecito, was twice convicted and twice exonerated for the murder of Kercher.

But despite the Italian Supreme Court throwing out the case for good in 2015, there are still many who believe Knox and Sollecito were part of the brutal killing during which Kercher was sexually assaulted, beaten and had her throat viciously slit.

"There are people who believe in my innocence and there are people who believe in my guilt and there's no in between," Knox said in the opening moments of the documentary.

"Either I'm a psychopath in sheep's clothing ... or I am you."

She also added that she is still confronted constantly by the headlines that the case made over the years.

"The whole world knew who I had ever had sex with," she said.

"Seven men and yet I was some heinous whore, bestial and sex obsessed and unnatural.

"I get into a line at the grocery story and the person behind me is like, 'Woah, it's you. I know you.'

And I really want to turn to them and say, 'Who the f*** are you?'"

In addition to Knox, Blackhurst and McGinn interviewed Sollecito, Italian prosecutor Giuliano Mignini - who is still firmly convinced of the pair's guilt - and Nick Pisa, a freelance journalist who broke the story in the UK's Daily Mail.

"It was very hard to talk to all of these people mostly because they had their guard up a little bit," said Blackhurst.

"People wanted to talk to them again (after the final exoneration) and were approaching them in very combative ways."

To convince each player of their intentions for a faithful portrayal Blackhurst and McGinn vowed to show them the final product prior to it screening anywhere publicly.

"No one had control over the editorial of the film," said McGinn.

"But we're proud that they all felt it was a fair and balanced look at the case."

The doco makers also approached Kercher's family who turned down the chance to state their piece. They too were sent a copy of the final film.

Included in that version is footage of Meredith's mother, Arlene Kercher, talking about her confusion and distress over the different legal conclusions that have been made throughout her quest for justice for her daughter.

"You can see the toll that this event and this story has taken on her," said Blackhurst.

"It was very important to include that (in the film) and to make sure people remember that there's a human side to this story that has been forgotten in many ways."
