Spectrum Now Festival program and bookingsSpectrum Now coverage and highlights
The producers of the documentary series Making a Murderer may produce a sequel to the controversial project which challenged America's justice establishment when it premiered in   December.
"We're prepared to continue to follow these cases and if enough story develops that warrants that to happen [we will]," Moira Demos told Fairfax Media. "Life goes on, the story is not over." 
The 10-part Netflix series examines the case of Steven Avery, a 53-year-old man from Manitowoc County, Wisconsin, who was found guilty in 1985 of rape, exonerated after almost two decades and then, stunningly, found guilty in 2005 of a second crime, murder. Avery is currently serving a sentence of life imprisonment without the possibility of parole.
The documentary brought the case into the media spotlight, compounding the embarrassment of the Manitowoc County district attorney's office, which had prosecuted both cases.
Demos and co-creator Laura Ricciardi are coming to Australia in   March to appear in an exclusive talk with Charlie Pickering at The Sydney Morning Herald Spectrum Now Festival presented by ANZ. Pickering, the festival's Talks ambassador, will interview the filmmakers on stage at The Star Event Centre on   March 10, followed by an audience Q&A.
It is the first time the pair has appeared on stage at a festival to discuss the film, and both see it as an opportunity to bring new context to the debate about the series, and about the inequalities in America's justice system.
"We're thrilled to have a more in-depth conversation, rather than a short interview or three minutes on a late night show, that's a different thing," Demos says. "To have the time to discuss the filmmaking, the process of making it, and what we can learn from it, that's very exciting. We made this series to start a dialogue and we want to be part of that dialogue."
Neither has been to Australia before.
"We're thrilled people so far away from where we live are watching the series and are connected to the story," Demos says. "We're excited to have an opportunity to come and speak to people about the series."
Demos and Ricciardi say the international reaction to the series was notably different to the reaction within the US, where the series drew criticism for what many felt was an attack on the US justice system.
"In the United States a lot of people like to point fingers and say this is what's going on in Wisconsin and are hesitant to think of it as an American story, and an American problem really," Demos says. "I think international audiences are more likely to view this as a story about America."
Ricciardi says the story transcends nationality: "I think of it as a human story." 
When Making a Murderer premiered in   December, the series attracted some controversy in the US, with key prosecution figures and some media outlets rounding on the filmmakers and accusing them of unfairly tilting the series to emphasise Avery's innocence.
"You don't want to muddy up a perfectly good conspiracy movie with what actually happened," prosecutor Ken Kratz told US media.
The filmmakers defend the series saying no documentary could have included every detail of the Avery case. Nor, Demos adds, was the documentary an attempt to re-litigate the case on television.
"That wasn't our goal in making this series; it's certainly not our goal now," she says.
The success of Making a Murderer is in part due to a broader wave of true crime programming, notably the hit podcast Serial and HBO's The Jinx, both of which took criminal cases and examined them in great detail.
Such programs "allow exploration of the underbelly of society and the part of society that doesn't get a lot of screen time or a lot of time in literature", Demos says. "I think people often are very curious about that and it opens up their eyes."
