Where was The Man In My Basement filmed? Complete guide to all filming locations and other production details

The Man in My Basement, a thriller directed and co-written by Nadia Latif in her feature directorial debut, is based on the novel of the same name by Walter Mosley, who also co-wrote the screenplay. The film stars Corey Hawkins, Willem Dafoe, Anna Diop, and Tamara Lawrance. It premiered in the Discovery section at the 2025 Toronto International Film Festival and was released in select theaters on September 12, 2025.

The story follows Charles Blakey (Corey Hawkins), an African American man in Sag Harbor, New York, who is struggling with bad luck and is about to lose his ancestral home when a strange white businessman with a European accent (Willem Dafoe) approaches him to rent his basement for the summer.

According to 4filming, The Man in My Basement was filmed in Cardiff and Carmarthenshire, Wales, despite the story being set in the United States. The locations were selected with the aim of being able to reproduce suburban Long Island as well as offer practical filming conditions.

As reported by the BBC, Marjorie Welsby, a resident of a Grade II-listed wooden property in Llandybie, Carmarthenshire, shared that the production team contacted her about filming on the property:

"We got a note through the door last year from someone saying they wanted to make a film in the area, we initially thought they just wanted shots of the house's exterior, but they ended up filming inside too, They stripped out our whole downstairs and put it in storage - all the fittings and furnishings - in order to turn it into an antiques and quilting shop for the shoot.''

She added:

''We managed to have a peek at what they'd done and it was a very strange feeling to walk into your own home and feel you've never been there before, but, by the time it was all over, everything had been put back in exactly the same place as where we'd left it."
