Trivia: The famous "Dukes of Hazzard" sequence was the filmmakers' wry commentary on the uncompleted state of Interstate 105, which had become a running joke among LA motorists. It was finally (and quite uncoincidentally) completed in late 1993 shortly before the film's release, years behind schedule.
Trivia: When the bus crashes into the plane at the end, the company logo on the plane is "Pacific Courier." This fictional company name also appears in "Die Hard"--it's on the truck the terrorists show up in (except Karl and Theo, who arrive by car). Jan de Bont, who directed "Speed," was DP on "Die Hard."
Trivia: Although Keanu Reeves states in the film that the freeway gap is 50 feet, the missing section shown in the digitally-retouched freeway shot is actually 177 feet, when measured against other known structures. Jan de Bont's digital effects team realised that a properly-measured 50-foot gap would appear far too small for the desired shot, so they made the gap more than three times larger.
