Christopher Walken was robbed at the airport in Venice and his The Prophecy II script, glasses, keys, drivers license, and $100 were stolen. All items were later found (including the script) except for the money.
Christopher Walken was one of two actors from the first film to reprise his role in this sequel. The other was Steve Hytner, who played the coroner. The characters of Thomas Dagget (Elias Koteas) and Lucifer (Viggo Mortensen) return; however, their appearances are very brief, and different actors play the roles.
