20 Things You Didn't Know About Heat
8. The Film Was Shot Entirely On Location With No Soundstages
Soundstages are used throughout the film industry both to shoot complex, CGI-heavy scenes which require enormous amounts of control, and also to create sets which the production simply can't find in reality.
However, Heat was uncommonly shot with the use of no soundstages whatsoever.
Despite filming for 107 days across an estimated 85 locations, everything you see in the movie was filmed on-location.
Mann tasked his location manager Janice Polley with trying to find as many locations as possible which hadn't been featured in films before, resulting in just 10 of the movie's locales having appeared in prior works.
The one location which challenged Mann above all other was, unsurprisingly, LAX, with the crew almost having to find a new stage for the finale after the Unabomber called in a bomb threat to the airport in June 1995.
