Amerika sparked much controversy from many camps long before it even aired. Many liberals dismissed the mini-series as right wing paranoia, while many conservatives complained that the Soviet brutality that was depicted was seriously underplayed. Several re-writes and production delays resulted. Many objected to it on the basis that it could damage American-Soviet relations. The United Nations publicly objected to the depiction of United Nations Peacekeeping Forces as a Soviet controlled occupying force. The Soviet government at one point threatened to shut down the ABC News Moscow Bureau if the mini-series aired (although this threat was never carried out.) This prompted ABC President John B. Sias to state "We're going to run that program come rain, blood, or horse manure."
The UNSSU compound raided in the movie was at an abandoned building outside of Lincoln, Nebraska. It stood on the grounds of a Nebraska state surplus site and remained in its "UNSSU" scheme (including large red lettering, white paint and burn marks) for many years until its demolition in August 2007.
The attack helicopters seen during the "Lincoln Week" parade were originally created for use in Blue Thunder.
In the scene where the assembled crowd recites the American Pledge of Allegiance, the extras had to be taught it since the miniseries was filmed in Canada.
