A portraitist, Bob Willoughby changed the way celebrities and films sets were documented by bringing photojournalism to Hollywood. When the American photographer was commissioned, in 1954, to photograph Judy Garland on the set of A Star is Born, he turned into a renowned photographer, requested by studios to produce images for the press. Yet, the most precious encounter had happened a year earlier when Bob Willoughby was asked to depict a new actress on her first visit to Hollywood. After meeting Audrey Hepburn, he considered she ‘took my hand like... well, a princess, and dazzled me with that smile that God designed to melt mortal men's hearts’. It marked the beginning of a lifelong association made of striking personal images of the actress preparing herself for a role or napping at home with her pet fawn. Bob Willoughby captured actors at their most vulnerable and intimate or their most theatrical exuberance, giving a candid and spontaneous insight into the « behind-the-scenes » where, until then, things had been highly staged and controlled.
