On an early tour of RKO, Welles met Seiderman in the small make-up lab that he created for himself in an unused dressing room. "Welles fastened on to him at once," wrote biographer Charles Higham, as Seiderman had developed his own makeup methods "that ensured complete naturalness of expression—a naturalness unrivaled in Hollywood." Seiderman developed a thorough plan for aging the principal characters, first making a plaster cast of the face of each of the actors who aged. He made a plaster mold of Welles's body down to the hips.
