 During filming, camera operator Karl Brown (I) (qv) was sure that  the movie was just another typical melodrama. At the films  premiere, D.W. Griffith (qv) had hired the entire Los Angeles  Philharmonic Orchestra to play the score for the film. Brown was  amazed; nothing like this has been done before. When the conductor  raised his baton, and the orchestra started playing, he said it was  so amazing and loud he was shaking his head, "It was like nothing I  ever heard." Brown additionally remembers that Griffith hummed  certain themes to the composer of the original score that he wanted.
