The morning after the film's L.A. premiere, Christian Slater reported to Ventura City jail to begin a 90-day prison sentence for drug offenses, assault and battery. He would be released after 57 days and enrolled in an anti-addiction program immediately after.
At the time of filming, the movie had the largest painted scenic backdrop ever used in a film.
Was originally titled "The Flood", but was changed, because the filmmakers didn't want audiences to assume it was primarily a disaster movie.
Many of the sets such as the cemetery where Tom hides the money in, were actually water tanks with sets built within them. This appeared on a "Making of" which was aired on HBO when the film had been released in 1998.
Director Mikael Solomon was hired to direct this film based on his work on James Cameron's grueling filming of "The Abyss" in which most of the sets were in underwater tanks much like this film required.
