Netflix has also released a trailer for the documentary, giving a glimpse at just over two minutes of footage from the series, including interviews and dramatic re-enactments, as well as archive footage.
The Disappearance of Madelaine McCann, a true crime doco in the same vein as Netflix hits Making a Murderer and Abducted in Plain Sight, is tipped to land in the United Kingdom on Friday, and claims to include testimony from more than 40 "experts" close to the 12-year-old case.
This documentary has been so highly anticipated and there has been a lot of controversy surrounding it.
Madeleine, three-years-old at the time, disappeared nearly 12 years ago during a family holiday in Praia da Luz, Portugal.
McCann disappeared on May 3, 2007, from the apartment where she was sleeping with her two-year-old twin siblings. The parents reportedly checked on the children throughout the evening until they discovered that Madeleine was missing at about 10 p.m.

Gamble believes we will find out what happened to Madeleine one day.
But, Netflix is still hopeful it'll follow in the huge success of other true crime dramas like Abducted In Plain Sight. Year on year DNA is getting better.
"And as we use that technology to revisit and review that which we captured in the past, there's every likelihood that something we already know will slip into position".
The McCanns previously released a statement distancing themselves from the series.
In a statement about the docu-series, the McCanns said: "We are aware that Netflix are planning to screen a documentary in March 2019 about Madeleine's disappearance".
Their spokesperson told The Guardian: "Kate and Gerry didn't ask for it and don't see how it will help the search for Maddie on a practical level, so they chose not to engage". They also confirmed, "Our views and preferences are not reflected in the programme".
The Disappearence of Madeleine McCann is streaming on Netflix beginning March 15.
