All of Us Strangers (2023)

One night in his near-empty tower block in contemporary London, Adam (a screenwriter, played by Andrew Scott) has a chance encounter with his mysterious neighbor Harry (Paul Mescal) that punctures the rhythm of his everyday life. As Adam and Harry get closer, Adam is pulled back to his childhood home where it appears his long-dead parents (Claire Foy and Jamie Bell) are both living and look the same age as the day they died thirty years before.
