Die Hard was based on a book. That book, the 1979 thriller Nothing Lasts Forever, was the sequel to a 1966 novel called The Detective, which was adapted as a film of the same name in 1968. That film starred none other than Frank Sinatra. Yes, Frank Sinatra once played John “yipee-ki-yay” McClane.

While the Die Hard-Nothing Lasts Forever-The Detective saga is the most revelatory who-knew-it-was-based-on-a-book story, there are many more. And one Redditor set out to pay homage to them, creating movie posters with the titles of the books they were adapted from swapped in. So Blade Runner becomes Do Androids Dream of Electric Sheep?, Total Recall becomes We Can Remember It For You Wholesale, and yes, Die Hard becomes Nothing Lasts Forever. See a few of the best entires above.
