But They Cut ...
Part of Die Hard's appeal is how perfectly its villains embodied the essence of sleazy-slick 1980s greed. They're basically a bunch of Gordon Gekkos, masquerading as freedom fighters in order to cover their billion dollar heist. However, in Roderick Thorp's Nothing Lasts Forever, which Die Hard was based on (what, you didn't know Die Hard was a novel first?), Gruber and co. really are gun-toting political activists. And they're also sort of the good guys.

"Who said we were terrorists? No, seriously, you're rewriting history."
The book opens with the John McClane character (Joe Leland in the book), heading to L.A. to visit his daughter Stephanie for Christmas. But when a group of terrorists, headed by Anton "Little Tony The Red" Gruber, seize the Klaxon Oil Building, where Stephanie works, a shoe-less Leland has to fight them to save her. However, it turns out that Klaxon Oil is secretly making millions of dollars illegally selling arms to the fascist Chilean government, and Gruber plans to steal documents to expose them before cracking their safe and literally throwing their blood money out the damn window. Also, Stephanie is a coked-out space cadet in a relationship with Ellis, whom you may remember from Die Hard as the most legendary douchebag in film history.
But hey, so what if the book had a little more moral complexity than the film -- what else would you expect? But everything finally goes batshit at the book's climax. Gruber falls out of the window holding onto Stephanie's bracelet, which is pretty much exactly what happens in the movie. However, unlike the movie, both Gruber and Stephanie plummet to their deaths.
