This week sees the release of the 5th Die Hard movie and the franchise has expanded over the years. However in 1988 the first Die Hard laid out a blueprint for the action genre that has been used more often than any other with the possible exception of the buddy cop formula. Die Hard is so ingrained in pop culture to the point films to this day are still described as "It's Die Hard in/on a *____*" right up to 2013 where we have two movies described as Die Hard in the White House. So what are everyone's favourite Die Hard "knock offs" that relocated the concept but did a damn good job in the process? My top 3: 1. Cliffhanger (Die Hard on a mountain) One of Stallone's best. The stunning scenery and inventive aerial heist along with the brutal showdown's with the various members of the mercenary crew set this one apart, and John Lithgow is fantastic as sneering sociopath Eric Qualen. 2. Air Force One (Die Hard on THE plane) The only film I can recall where the President is an action hero. Sure it has some atrocious CGI at the end but for the most part it is a tense action thriller with smarts, good fight scenes and two quality actors in Ford and Oldman, at the top of their games. 3. The Rock (Die Hard on Alcatraz) Yeah I know a lot here hate Michael Bay, but I find most of his movies entertaining with great action and The Rock is still his best to date IMO. A big San Fran car chase homage to Bullit, that shower room shootout massacre, the mine car sequence, a morally grey villain played by the always quality Ed Harris, Nic Cage as a nerdy hero and Sean Connery spitting out great sarcastic one liners as a badass old British agent and the only man to have ever escaped Alcatraz, glorious stuff!
