‘Die Hard’ Was A Sequel To ‘Nothing Lasts Forever’ Starring Frank Sinatra
The original screenplay for Die Hard was based on the 1979 novel Nothing Lasts Forever by Roderick Thorp, which tells the story of German militants taking over a Los Angeles office block. And due to its connection, Fox was contractually obligated to offer the lead role to Frank Sinatra, who was in his 70s at this time. He passed on it.
