20 Psychological Thrillers You Must See Before You Die

20. Rosemary's Baby

One of those that merges meticulously into horror, Roman Polanski's Rosemary's Baby is an astonishingly tight, atmospheric thriller, one that takes the thought of an unthinkable event (later mirrored in The Omen) and amplifies the terror surrounding it, creating one of the most disquieting films in the canon in the process. Elevated into greatness mostly through Polanski's virtuoso direction (something he would later perfect in Chinatown, my contender for the greatest film of all time and one that could've easily appeared on this list alongside other Polanski classics like The Tenant or Repulsion), Rosemary's Baby is helped immeasurably by a scattergun star performance from Mia Farrow as the titular Rosemary, whose growing paranoia about the fate of her baby begins to control her life.
