Two decades after the shocking murder of a young beauty queen captivated and divided a nation, director Kitty Green crafts a uniquely unsettling exploration of myth, memory, and media obsession in "Casting JonBenet". Rather than re-investigate the crime itself, the film turns its lens on the community still living in its shadow, observing a series of actors from the Boulder, Colorado area as they audition for roles in a hypothetical film about the case. As performers like Hannah Cagwin, Aeona Cruz, and Liv Bagley prepare their readings, they reveal their own personal connections, deeply held theories, and the ways this singular tragedy has woven itself into the local fabric. This provocative documentary blends audition tapes, intimate interviews, and staged scenes, creating a haunting mosaic that questions how truth is constructed in the age of true crime spectacle, all while the ghost of a little girl lingers in every frame.
