The Hunt for Red October, Patriot Games, Clear and Present Danger, and The Sum of All Fears have been turned into commercially successful films with actors Alec Baldwin, Ben Affleck, and Harrison Ford as Clancy's most famous fictional character Jack Ryan, while his second most famous character John Clark has been played by actors Willem Dafoe and Liev Schreiber. All but two of Clancy's solely-written novels feature Jack Ryan or John Clark.
The first NetForce novel was adapted as a television movie, starring Scott Bakula and Joanna Going. The first Op-Center novel was released to coincide with a 1995 NBC television mini-series of the same name (Tom Clancy's Op-Center) starring Harry Hamlin and a cast of stars. Though the mini-series didn't continue, the book series did, but it had little in common with the first mini-series other than the title and the names of the main characters.
The website IMDb reports that Tom Clancy's novel Without Remorse is to be made into a movie and is expected to be released in 2011.
With the release of The Teeth of the Tiger, Clancy introduced Jack Ryan's son and two nephews who were main characters; these characters continue in his latest novel, Dead Or Alive.
Clancy has written several nonfiction books about various branches of the U.S. armed forces (see non-fiction listing, below). Clancy has also branded several lines of books and video games with his name that are written by other authors, following premises or storylines generally in keeping with Clancy's works. These are sometimes referred to by fans as "apostrophe" books; Clancy did not initially acknowledge that these series were being authored by others, only thanking the actual authors in the headnotes for their "invaluable contribution to the manuscript".
In 1997, Clancy signed a book deal with Penguin Putnam Inc. (both part of Pearson Education), that paid him US$50 million for the world-English rights to two new books. He then signed a second agreement for another US$25 million for a four-year book/multimedia deal.Clancy followed this up with an agreement with Berkley Books for 24 paperbacks to tie in with the ABC television miniseries Tom Clancy's Net Force aired in the fall/winter of 1998. The Op-Center universe has laid the ground for the series of books written by Jeff Rovin, which was in an agreement worth US $22 million bringing the total value of the package to US$97 million.
