Bérard showed his first exhibition in 1925, at the Gallery Pierre. From the start of his career he had an interest in theatrical scenery and costume designs, and played an important role in the development of theatrical design in the 1930s and 1940s. In the early '30s Bérard worked with Jean-Michel Frank, painting screens, wood-work and drawing projects for carpets. He also worked as a fashion illustrator for Coco Chanel, Elsa Schiaparelli, and Nina Ricci. Bérard's most renowned achievement was probably his lustrous, magical designs for Jean Cocteau's film La Belle et la Bête (1946).
