About My Sister's Serial Killer Boyfriend
Maddie, a local reporter investigating a series of killings targeting similar looking women is caught off guard when her younger sister Olivia, is attacked in her own home. Urging on the side of caution, Maddie suggests they take a self-defense course. When Olivia starts to fall for their instructor, Maddie becomes skeptical when he refuses to reveal anything about himself, and tries to intervene before the relationship turns into a deadly obsession.
Directed by Danny J. Boyle, My Sister's Serial Killer Boyfriend leans on a strong ensemble — Brianna Cohen, Rib Hillis, Revell Carpenter — to carry a story that balances spectacle with character.
The film landed with audiences for its craft and performances, and remains one of the most talked-about thriller titles of 2023.
