Testemunha de Acusação

Charles Laughton, who could be moody and difficult, was apparently a dream to work with, throwing himself into the role with dedication and delight. Billy Wilder later recalled a day that was set aside just for shooting reaction shots of the jury and courtroom crowd (composed of extras hired only for the day). Normally, the assistant director would read the actors' lines, and the extras would react. However, Laughton, who was fascinated with the whole process of filmmaking, begged to help. So he came in on his day off and read all of the off-camera speeches to the jury members. He not only read his part but also the judge's, the prosecutor's, and even Marlene Dietrich's. According to biographer Maurice Zolotow in his book "Billy Wilder in Hollywood", "it was an exhibition of craftsmanship such as Wilder had never seen. He believes that Charles Laughton had the greatest technical range and power of any actor, man or woman, whom he has known."
