Inchiesta pericolosa

Frank Sinatra played Detective Joe Leland from the novel "The Detective" by Roderick Thorp. Thorp wrote a sequel ("Nothing Lasts Forever") in which Leland is trapped in a Claxxon Oil Corporation skyscraper after it's taken by German terrorists and must rescue his daughter and grandchildren. Twenty years later the novel was filmed with some changes: the daughter became his wife, Claxxon became the Nakatomi Corporation, Joe Leland's name was changed to John McClane, and the film was released under the title Trappola di cristallo (1988). Because of a clause in Sinatra's contract for "The Detective," which gave him the right to reprise his role in a sequel, he was actually the first person offered the McClane role even though he was 73 years old at the time. Also, coincidentally, Bruce Willis (who played McClane) made his movie debut in Delitti inutili (1980), walking out of a bar as Sinatra walked in. Additionally, Lloyd Bochner played Dr. Wendell Roberts in this movie. His son, Hart Bochner, played Harry Ellis in Trappola di cristallo (1988). Finally, Jacqueline Bisset's then partner, Alexander Godunov, played a villain in Die Hard.

When Joe is depicted first visiting the beach house of Dr. Roberts, the view in the distance is of the California coast. The film takes place in and around New York City and Long Island.
