You thought you’ve seen the last of him. Yes, John McClane is back with the latest Die Hard flick and it begs to ask the question: why won’t Die Hard die?

When sequels have the lifespan of a fish’ memory, when scriptwriters burn the midnight oil to come up with an original sequel twist, when producers can only dream of matching the original’s box office receipts, Die Hard seems to be the ultimate guide to a good action movie and just keeps earning more money in every release using the same aging actor, storyline and, you guess it, one-liner. Yippee-ki-yay! Americans just can’t live without Die Hard and we spell out five reasons why.

Moviegoers pay more cash to watch the latest sequel. With the highly efficient strategy to improve their revenue producers invest more for every sequel that the fourth film costs nearly four times than the original. And even the Smithsonian Institution loves John’s undershirt, which always starts in the film as pearly white and ends up greasy and messy. You’d think the shirt will go straight to the laundry; nope, it’s now in the venerated museum along with Lincoln’s top hat.
