During the 1960s, Warhol also groomed a retinue of bohemian and counterculture eccentrics upon whom he bestowed the designation "Superstars", including Nico, Joe Dallesandro, Edie Sedgwick, Viva, Ultra Violet, Holly Woodlawn, Jackie Curtis, and Candy Darling. These people all participated in the Factory films, and some—like Berlin—remained friends with Warhol until his death. Important figures in the New York underground art/cinema world, such as writer John Giorno and film-maker Jack Smith, also appear in Warhol films (many premiering at the New Andy Warhol Garrick Theatre and 55th Street Playhouse) of the 1960s, revealing Warhol's connections to a diverse range of artistic scenes during this time. Less well known was his support and collaboration with several teenagers during this era, who would achieve prominence later in life including writer David Dalton, photographer Stephen Shore and artist Bibbe Hansen (mother of pop musician Beck).
