A still from Lockbox (2026), the supernatural horror film starring Carla Gugino directed by Daniel Stamm

Lockbox opens July 3. Carla Gugino plays Ellen, a woman who takes in her traumatized cousin Winthrop, only to find something supernatural has been hunting him for a long time.

Daniel Stamm directed The Last Exorcism. His signature is quiet dread that builds before anything visible arrives on screen. That approach is fully on display here.

For fans of horror with a strong actor at the center. Gugino carries this one and the early reviews say she earns it.

Watch The Last Exorcism the night before. Or revisit The Haunting of Hill House to see Gugino at her most unsettled.

The kind of horror film you are still picking apart on the drive home.
