Referencing the movie's futuristic premise itself, there were many societal or political forecasts woven into the storyline, and a number of these have become reality since the movie's release, including: The People's Republic of China embraces capitalism and becomes a global economic superpower. Nike becomes a huge multinational corporation. The collapse of the Soviet Union occurs. A governor of California is elected president. The prevalence of reality shows on television. Network television deals with previously forbidden subjects accepted as normal. People in the 21st century began living increasingly in vans and RVs to make up for the cost of expensive housing and property taxes.
Some actors listed in the opening credits are not seen in the movie and were apparently edited out.
