released in the late 30s, censors demanded it be removed on the  grounds that it was blasphemy. A loud clap of thunder was  substituted on the soundtrack. The dialogue was partially restored  on the video release, but since no decent recording of the dialogue  could be found, it still appears garbled and indistinct. The  censored dialog was partially returned to the soundtrack in the  initial "restored version" releases. Further restoration has now  completely brought back this line of missing dialog. A clean  recording of the missing dialog was reportedly found on a Vitaphone  disc (similar to a large phonograph record). Modern audio technology  had to be used to insert the dialog back into the film without any  detectable change in the audio quality.
