** Plans were in motion to adapt ''Literature/TheCardinalOfTheKremlin'', which would have been a direct sequel to ''Film/TheHuntForRedOctober''. However, various plans to adapt the novel into a script failed, allegedly because the material (which revolved around "spy games" and espionage in Russia set against The UsefulNotes/ColdWar) was too difficult to adapt for the screen. Various press reports also suggest that efforts were made to adapt ''Literature/DebtOfHonor'' (which was released in 1996) and ''Film/TheSumOfAllFears'', but this never got past the drawing board, and both Creator/HarrisonFord and director Creator/PhilipNoyce officially abandoned the potential sequel in 2000. ''Sum of All Fears'' was subsequently given a ContinuityReboot and was released in 2002.

** A subplot involving Cathy Ryan performing experimental eye surgery on a child was filmed, but cut from the final film.
** The first draft of the script was written by Creator/JohnMilius, and allegedly it was faithful enough to the book that Creator/TomClancy loved it. This script was ultimately discarded because, just like in the book, Jack Ryan barely appears in the first half of the story (instead the first half of the story is mainly about John Clark and the American soldiers in Colombia) and the studio wanted Jack Ryan to be at the center of the story (they feared that if Jack Ryan's role wasn't big enough, Creator/HarrisonFord would not agree to star).

* StockFootage: Footage shot for this film, featuring the F-18 Hornet, was used for 10 seasons in the opening titles on the Creator/Paramount series ''Series/{{JAG}}''. Footage from the convoy ambush scene was also used by ''JAG'', in the first season episode "War Cries" (with careful editing to remove Creator/HarrisonFord in a suit and insert David James Elliot in Navy Whites).

* RetroactiveRecognition: Donald Moffat had previously portrayed would-be President Lyndon B. Johnson in ''The Right Stuff''.

* DisownedAdaptation: Tom Clancy was very critical of the film adaptation of ''Clear and Present Danger''. Most notably, he disliked the ending. In the movie, Ryan blows the lid off the covert operation in Colombia by publicly testifying before Congress. In the book, the men responsible for the operation are quietly dealt with behind the scenes. Tom Clancy feels that Jack Ryan would never take a course of action that would result in the United States being damaged by a major scandal.
