Jake Gyllenhaal re-teams with his Prisoners director, Denis Villeneuve, in this sexy and hypnotically surreal psychological thriller that breathes new life into the dopplegänger tradition. Adam Bell (Gyllenhaal) is a glum, disheveled history professor, who seems disinterested even his beautiful girlfriend, Mary (Laurent). Watching a movie on the recommendation of a colleague, Adam spots his double, a bit-part actor named Anthony Clair, and decides to track him down. The identical men meet and their lives become bizarrely and irrevocably intertwined. Gyllenhaal is transfixing as both Adam and Anthony, provoking empathy as well as disapproval while embodying two distinct personas. With masterfully controlled attention to detail, Villeneuve takes us on an enigmatic and gripping journey through a world that is both familiar and strange—and hard to shake off long after its final, unnerving image.
