How Much Do You Know About the “Die Hard” Movies?

Bruce Willis plays John McClane, an NYPD detective known for taking out bad guys and doling out great one-liners. You probably know Martin Riggs from "Lethal Weapon," Harry Tasker from "True Lies" and Axel Foley from "Beverly Hills Cop."

The first terrorist that McClane kills in Nakatomi Plaza just happens to be Karl's brother, Tony. The result of that is Karl becomes enraged and pursues McClane with an unusual vengeance throughout the film.

You may remember the curious joke of the two FBI agents being introduced as Agent Johnson and Agent Johnson. Elsewhere in the movie, there's also a brief newcast in which we meet a reporter named Harvey Johnson. Word is the three Johnsons were included as a bit of a joke at the expense of co-star Reginald VelJohnson.

McClane discovers that there are sneaky things going on when he fires a gun that belonged to one of Major Grant's men and realizes the rounds are fake. The entire firefight was staged, and Grant is actually a villain.

When we meet Sergeant Al Powell in "Die Hard," he's buying Twinkies. Thanks to that scene and some throwbacks to it later on, fans routinely toss Twinkies at the actor while sharing lines from the movie.

Bruce Willis is in every "Die Hard" film but few other actors make the transition from one part to another. That said, Bonnie Bedelia as Holly Genarro, Reginald VelJohnson as Al Powell and William Atherton as Richard Thornburg were all in parts 1 and 2.

In order to mess with the terrorists, McClane sent the body of the terrorist named Tony back to Hans Gruber and the rest of the crew with a message on his sweater that said: "Now I have a machine gun — ho ho ho."

The police in New York are sent on a wild goose chase by Simon Gruber to find a bomb in a school. When the bomb is discovered, the police are too late and the liquids mix and then — boom — it's pancake syrup. Even Simon isn't evil enough to blow up a school.

When McClane first runs across Sam Jackson's character he hears a character say "Hey, Zeus" and mistakenly believes that his name is "Jesus." He is later corrected that the name is actually just "Zeus" like the Greek god.

Hans Gruber, played by Alan Rickman, has the most memorable death in "Die Hard" as he falls from a window. That look on his face was genuine shock since the director told Rickman he'd be safely dropped at the count of three and then dropped him early.

McClane is informed that what Thomas Gabriel is trying to pull off is called, in hacker parlance, a "fire sale." Why this term? Because like a real fire sale, everything must go, only in this case they mean the computerized infrastructure of the whole country.

Mary Elizabeth Winstead was cast as grown-up Lucy McClane in "Live Free or Die Hard." She reprised her role in the following "A Good Day to Die Hard," but she was cut from most versions of the film, including the director's cut.

Much of the action in "A Good Day to Die Hard" takes place in Russia, and that includes a trip to Chernobyl where the bad guy actually has a massive amount of weapons-grade uranium stored.

Bruce Willis came up with the "yippee-ki-yay" line as a joke. He told Ryan Seacrest it was literally just to make the crew laugh and he didn't expect it to be in the final cut of the movie at all.

The script that became "Die Hard with a Vengeance" started life as a script entitled "Simon Says." Warner Brothers originally envisioned it as another installment in the "Lethal Weapon" franchise. It was also meant to be a vehicle for Brandon Lee.

If John McClane has a catchphrase, then this is it. He utters the line "yippee-ki-yay" complete with a notable expletive in every one of the "Die Hard" films. The line is often cited for being one of the most memorable lines in film history.

John McClane Jr. joins his dad in the 5th "Die Hard" film as the father-and-son duo fight terrorists in Russia this time as opposed to stateside like n the previous four "Die Hard" films.

Across the five "Die Hard" movies that have been made so far, no one besides Bruce Willis has been involved in every single one of them. At the end of the day, you really only need Bruce Willis, though.

The phrase "yippee-ki-yay" became a low-key catchphrase from "Die Hard," and in part two it was paired with a fairly strong curse word. To make it safe for TV audiences, it was turned into the curiously worded "yippee-ki-yay, Mr. Falcon."

In John Leguizamo's autobiography, he wrote that he originally had a much bigger part in "Die Hard 2" until producers saw how short he was. His role was drastically cut, and the one line of dialogue he had ended up being dubbed by another actor.

Many actors were offered the role of John McClane, including Frank Sinatra, Arnold Schwarzenegger, Sylvester Stallone and others. Bruce Willis was mostly known for comedy at the time and was considered a long-shot option.

Kevin Smith shows up in a fun cameo as a computer whiz who goes by the name Warlock. The character's "real" name is Frederick Kaludis and, as you might guess, he lives with his mom.

Argyle apparently had nothing better to do, so he offered to wait around and see if McClane needed a ride or not. Then he gets locked in by the terrorists and can't leave, which does give him the opportunity to take one of the terrorists out later.

That giant bear was actually owned by director John McTiernan, who later included it in another film he directed, "The Hunt for Red October." In that film, the character of Jack Ryan takes the bear home with him.

While Simon keeps all the cops in New York busy hunting a bomb, his real plan is to rob the Federal Reserve Bank of New York for a mind-boggling $140 billion in gold bullion, which they make off with in dump trucks.

"Die Hard" was Alan Rickman's first film role, and he had not developed a knack for handling prop weapons. Every time he used one, he flinched involuntarily, so the director took to cutting away from him every time he did so.

The most recognizable song in the first film's score is Beethoven's Ninth Symphony, fourth movement. The film's composer didn't want to use Beethoven at all because he felt it was inappropriate, but the director convinced him by showing him Stanley Kubrick's "A Clockwork Orange," which used the same music.

On the set of "Live Free or Die Hard," the stunt double for actress Maggie Q got too close to Willis with a kick. She tagged him right in the face with a stiletto heel, and the wound was bad enough that the director claimed he could see bone exposed.

Bruce Willis and Sam Jackson have been in 5 films together — "National Lampoon's Loaded Weapon," "Die Hard with a Vengeance," "Pulp Fiction," "Unbreakable" and "Glass."

The first round of posters for the movie was released showing only the title and Nakatomi Plaza. Bruce Willis was nowhere to be seen because the studio was not convinced anyone would care to see a movie with Bruce Willis in it.

Sam Neill, arguably best known for his part in "Jurassic Park," was the first choice for the villainous Hans Gruber. Neill turned the role down, and then the casting directing happened to see Alan Rickman in a stage production of "Dangerous Liaisons." The rest is history.

In both "Die Hard" and "Die Hard with a Vengeance," the villains are German but the actors were not. The result is that much of the German dialog was hard to understand or, in some cases, total gibberish. It was dubbed over with proper German later on.

The novel "58 Minutes" by Walter Wagner was the source for "Die Hard 2." It had nothing to do the novel the first movie was based on at all. Interestingly, the novel was about a cop who has to save his daughter's plane from crashing, while the first novel was about a cop attending his daughter's office Christmas party, and neither movie used the daughter part.

In the unused ending, Simon gets away with the gold and McClane gets fired and loses his pension. Obsessed with finding Simon, McClane tracks him all the way to Hungary, and the two play a game of Russian Roulette with a rocket launcher. McClane wins.

Roderick Thorpe's novel "Nothing Lasts Forever," published in 1979, was the basis for the original "Die Hard" film. In the novel, retired detective Joe Leland is visiting the office building where his daughter works when terrorists take it over.
