Britt Lower has been cast in the lead role of Sender, a psychological horror film currently in production and produced by Jamie Lee Curtis through her banner Comet Pictures. The film will also feature performances by David Dastmalchian, Anna Baryshnikov, and Curtis.

The project marks the feature directorial debut of Russell Goldman and is based on his 2022 short film Return to Sender, which won awards on the festival circuit. Goldman later adapted the short into a feature-length screenplay that appeared on the 2023 Black List. The story centers on a woman who becomes entangled in a personal and unsettling e-commerce scam, triggering an obsession with uncovering the identity of the anonymous sender.

Curtis is producing the film alongside Molly Hallam and Jake Katofsky. Executive producers include Akshay Shah, Lower, and Goldman. Co-producers on the film are Thomas Grabinski, Eric Baird, Cesar Vega, and Mireia Vilanova. Verve Ventures is representing the film for North American sales.
