Does 'My Sister The Serial Killer' Have A Movie Adaptation?

Nope, no movie yet for 'My Sister the Serial Killer', which is a shame because it’s got all the ingredients for a killer thriller—no pun intended. The book’s short, punchy chapters would fit perfectly into a tight 90-minute film. I can already picture how they’d shoot Ayoola’s Instagram-perfect crimes juxtaposed with Korede’s grim clean-up details. The novel’s exploration of beauty and violence feels tailor-made for visual storytelling. Until Hollywood or Nollywood picks it up, we’ll just have to keep recommending the book to everyone who loves dark comedies with bite.

it's one of those novels that sticks with you long after you finish it. The story’s dark humor and tense sibling dynamics make it ripe for a cinematic adaptation, but as of now, there isn’t a movie version. The book’s unique blend of thriller and family drama would translate brilliantly to the screen, though. Imagine the visual contrast between Lagos’s vibrant streets and the chilling acts Korede covers up for Ayoola. The tension in scenes like the hospital corridors or the dinner with Tade could be so gripping in film form. I heard rumors a while back about production companies showing interest, but nothing concrete has materialized. The author, Oyinkan Braithwaite, has a sharp, minimalist style that would challenge filmmakers to capture the book’s tone without relying too much on dialogue. It’s the kind of project that could attract a director like Dee Rees or Kasi Lemmons—someone who understands nuanced female relationships and societal pressures. Until then, we’ll have to settle for rereading the book and imagining how that final confrontation might look in a climactic shot.

What’s fascinating is how adaptable the story’s themes are globally. The core idea—sibling loyalty vs. moral duty—resonates across cultures, which might explain why the book gained such international traction. A film adaptation could delve deeper into Lagos’s social hierarchies or expand Korede’s backstory visually. The novel’s brevity works in its favor; a screenplay wouldn’t need drastic cuts. If done right, a movie could even enhance the original by showing Ayoola’s charm through body language or using color palettes to mirror Korede’s internal conflict. For now, fans like me are left speculating about casting choices (Adesua Etomi-Wellington as Korede? Or maybe Thuso Mbedu?) and hoping some studio greenlights this soon.
