This week marks the 25th anniversary of Die Hard. At the time, the studio took a risk on Bruce Willis as an action star. It was a gamble that paid off huge and led to four sequels and the masculinizing of the phrase, "Yippee kay yay."

Check out the write up over at Screen Crush that describes the bizarre inspiration for one of the greatest action films of all time, and how the role of John McClane was offered to and rejected by many unlikely choices -- including Frank Sinatra. Weird, but it would have been amazing to see Old Blue Eyes with a machine gun.

Happy birthday, Die Hard. You are now old enough to rent a car. Then use it to kill a helicopter.
