B&W 50's Movie that has NO talking..

It's driving me crazy trying to find out what the name of it was....What is the black and white movie that has

NO DIALOG ???...

I remember it as a spy type plot.
You could follow the story by following the proceedings...it had sound...just no verbal exchanges....I thot it was VERY creative....might have been a Ray Milland film ?

Can anyone help me out ? GumManRay@aol.com
