First film featuring John Le Mesurier (uncredited).
There is a complete mismatch of the stock footage of the two trains which are used to indicate the murderers means of transport following the murder - the engines are two totally different class locomotives.
Opening credits prologue: This story is true . . . . .
By that we do not mean these events actually happened. We mean that it is a story of real newspaper life.
While you sleep in your beds the news of the world is collected, sifted, investigated and presented by mechanical means at your breakfast table.
This is primarily a film to show how that comes about. The story selected is an old one. Murder . . . . .
But every murder story is front page news for a newspaper. And if this film helps you to know how that news appears on the breakfast table, it will have achieved its object . . . . . . .
