Part of my search about movie coverage of the atomic bomb. This doesn't mention anything about the horrific nature of the bomb, only the arms race and espionage about it during the war.

We've seen aspects of this in other films/shows since: the simple "luxuries" of living in the Western world opening the eyes of Soviet operatives stationed here. The laughable part: the "luxury" is pretty shabby. 

This is an ok thriller. It lacks a good cast after DA & GT. JH is mostly wasted here, and the Soviet baddies are only semi-familiar faces.

United States v. Paramount Pictures, Inc., 334 U.S. 131 (1948) was decided May 3, just over a week before this release.
