How did he get out?

Rating: 10/10 (19 January 2005)

Does anybody know who rescued James Stewart off the ledge that he is seen hanging on to in the opening of the picture? It is never explained at all. There is no way he could have held on much longer without taking a dive.
I have just purchased the DVD with extras on it and still regard it a great film. It is hard to believe that Vera Miles was going to be the star of this picture and only lost out owing to pregnancy. I also find it strange that the music was conducted in this country by Muir Matheson and not in Vienna where it was supposed to be owing to the strike by musicians in America.
