[Help with Film Title]

Thanks for the suggestion. I'll try to check it out.

[Help with Film Title]

I only remember one scene which occurs at or near the end of the movie. A man walking down a street is followed by several agents (German or Russian). He goes into a hotel / boarding house (which I think is adjacent to a train stop) while the others wait outside for his return. He escapes through a window and plants a bomb in a car located in the garage out back. When the bomb explodes, the agents go to investigate and he evades them. He then gets a taxi that takes him to an old house where the agent?s headquarters is located. I believe this was a B/W movie and seemed to be filmed in the 50?s to 60?s time period.
