Identical triplets become separated at birth and adopted by three different families. Years later, their amazing reunion becomes a global sensation but also unearths an unimaginable secret that has radical repercussions.
Like Morris's work, the film has an abstract side as well as a concrete one, carrying a unique story to a point where broader philosophical issues open up.
Wardle has pulled off an interesting feat. He has told these brothers' story, raised infuriating questions about the abuses of science, and by the end challenges the viewer to wonder about what makes us all tick.
The intriguing, sobering and compellingly strange slice of real life carved out by Three Identical Strangers amounts to one of the best non-fiction features of 2018.
A documentary with a story so outlandish it might well have been rejected by a Hollywood studio had a screenwriter pitched it as the basis of a fictional movie.
The less you know about Three Identical Strangers going in, the better, so don't read this part until after you've seen the movie. And you should see it, because it's brilliantly made and contains riveting material.
Those familiar with the story of the triplets will find plenty to be shocked and moved by in Three Identical Strangers, and those with no knowledge of the familial break-up and continuing fall out will be blown away and left with plenty to think about.
Footage that was at first celebratory is seen again as a form of reckoning, and the moment where the narrative breaks the frame of individual interviews for a reunion is heart-rending.
Wardle takes his audience on an engrossing, heartbreaking journey into the lives of three innocents whose lives became experiments for scientists on a quest to unravel how identity is shaped.
