Laura Ricciardi and Moira Demos spent ten years making Making A Murderer.

Making A Murderer is the controversial 'true crime' series that has proved an unlikely global success.

It takes us through one man's journey of an 18-year prison sentence for violent crime, his release after being exonerated through DNA evidence - and then his return to jail, after being convicted of murder in a separate case.

Film-makers Laura Ricciardi and Moira Demos tell BBC Breakfast why it took ten years to make.
