The poetry written by Simon Templar's long-haired artist character, Thomas Moore, was actually written by Val Kilmer.
Simon uses a Nokia 9000 Communicator cell phone. This phone was very cutting-edge when it was introduced in 1996, as it functioned as both a handheld phone and a clamshell pocket computer, complete with a mini-QWERTY keyboard, and several built-in apps.
The voice of the radio announcer at the end of this movie was Sir Roger Moore, who played The Saint (1962) on British television. The announcer mentions the United Nations Children's Fund (UNICEF), as one of the charities that have been given major donations. Moore was heavily involved with UNICEF.
Val Kilmer turned down returning to the Batman franchise after the box-office smash Batman Forever (1995) due to his commitment to this movie.
While filming in Oxford, England, the producers had the Bodleian Library (the main library of The University of Oxford) closed to the public for several days. This caused much complaint in the University, as a large proportion of the students were studying for exams.
