Curiously, it's quite the opposite of what you might think (as Darren notes above)! Good Day to Die Hard is the first script which originated as a script for a Die Hard, including Die Hard, which was supposed to be the sequel to the Frank Sinatra flick The Detective. Die Hard 2 was originally written as a stand-alone film based on a novel called 58 minutes. Vengeance was originally written as a Brandon Lee vehicle that was then picked up as a potential Lethal Weapon 4. Live Free was a tech article adaptation that was supposed to be a high-tech thriller.
