Sidney Lumet, from Making Movies:
The sound editor on Murder on the Orient Express hired the “world’s greatest authority” on train sounds. He brought me the authentic sounds of not only the Orient Express but the Flying Scotsman, the Twentieth Century Limited, every train that had ever achieved any reputation. He worked for six weeks on train sounds only. His greatest moment occurred when, at the beginning of the picture, the train left the station at Istanbul. We had the steam, the bell, the wheels, and he even included an almost inaudible click when the train’s headlight went on. He swore that all the effects were authentic. When we got to the mix (the point at which we put all the sound tracks together), he was bursting with anticipation. For the first time, I heard what an incredible job he’d done. But I had also heard Richard Rodney Bennett’s magnificent music score for the same scene. I knew one would have to go. They couldn’t work together. I turned to Simon. He knew. I said, “Simon, it’s a great job. But, finally, we’ve heard a train leave the station. We’ve never heard a train leave the station in three-quarter time.” He walked out, and we never saw him again.
I feel great sorrow for this man.
