Trivia: The movie was a not so subtle plug for Apple/Macintosh. The director/producer Irwin Winkler is a "Mac man." All the personal computers Angela uses are Macs. Even at the end, the computer conference was filmed at the Moscone center in San Francisco and is a tribute/simulation to the main MacWorld conference which is held every January at the Moscone. The plot is based on the good guys using Macs and the bad guys on PC's/Windows. Still today, but especially raging back in the 1990's, was the huge Mac rivalry with Windows.
Trivia: While walking the beach, Devlin wraps his handkerchief around Angela's waist. Cary Grant did the same thing in the film "Notorious", where he played a character named Devlin.
