Screen Tests are a series of short, silent, black-and-white film portraits created by Pop artist Andy Warhol between 1964 and 1966. Filmed primarily at the Factory, the portraits generally depict their subjects from the neck up against plain backdrops. Of the approximately 500 Screen Tests Warhol produced, 472 survive, featuring a wide range of Factory regulars and visitors, many of whom were prominent figures in the downtown New York cultural scene of the 1960s. The films represent a new form of portraiture, presenting a slowly moving image of a person. They connect both to Warhol's experimental films, emphasizing stillness and duration, to his broader interest in documenting the personalities who comprised his social and artistic milieu.
