Billy Zane ended up in this movie due to a mistake made by his agent. Zane had read the script for a different movie called "The Taxman", and his told his agent he would meet with the producers. His agent accidentally hooked him up with the producers of "Taxman", a totally different script. They didn't figure out the mistake until halfway through the meeting, but Zane agreed to do the movie anyway.
As the movie poster here on IMDB shows, this movie has also been released under the title "Nothing to Declare".
