How do you adapt a popular non-fiction book for the big screen? In beefy biopics like Oppenheimer - based on the critically lauded doorstop American Prometheus: The Triumph and Tragedy of J Robert Oppenheimer – the filmmakers are usually gifted a literal character arc.
For more abstract best-sellers – like the stat-filled baseball analysis Moneyball or the jargon-heavy subprime mortgage investigation The Big Short, both adapted into award-winning movies – it feels like screenwriters try and find a narrative thread or two to latch onto, then just simplify and streamline the rest of the material to make it digestible.
With her latest film Origin, Ava DuVernay (director of the Oscar-winning civil rights drama Selma and the excellent Netflix miscarriage of justice mini-series When They See Us) has taken a notably different approach. It is inspired by Caste: The Origins of Our Discontents, the 2020 bestseller by Isabel Wilkerson, a veteran reporter and essayist who in 1994 became the first African American woman to win the Pulitzer Prize for journalism.
In her book Wilkerson seeks to reframe the discussion of race and racism in the US by examining historical hierarchies on a global and historical scale. The key element is power: those who have it, and how they aggressively keep hold of it by creating societal divisions and powerful social stigma.
It is an elegantly written and persuasively argued book full of Wilkerson’s contemporary reportage and illuminating case studies from the past, some of which are dramatised for the film.
But Origin is also a biopic of Wilkerson herself, played with extraordinary commitment by Aunjanue Ellis-Taylor, (who was Oscar-nominated in 2022 for her role opposite Will Smith in tennis biopic King Richard as watchful mother Oracene Williams). As well as outlining the key arguments of the book,
Origin seeks to explore the extraordinarily stressful personal circumstances that compelled Wilkerson to pursue writing it.
