NYPD Detective John McClane (Bruce Willis) has faced some brutal terrorists in his career, but now, he's about to face what may be his most dangerous enemy yet. McClane receives a call to bring in a hacker named Matt Farrell (Justin Long), because there has been a breach in an FBI computer system. Farrell is one of the many hackers who are suspected in the attack, and all known hackers are to be questioned. But after McClane gets to Matt's apartment, a group of men show up and try to kill McClane and Matt, who barely escape with their lives. As it turns out, a group of terrorists led by Thomas Gabriel (Timothy Olyphant) are systematically shutting down the United States computer infrastructure. Hilarity ensues when they crash the stock market, crippling America's economy. It turns out that Matt knows enough about hacking to know exactly how Gabriel is shutting down the USA. Gabriel, a disgraced former Department of Defense employee, plans to bring the country to its knees, but he doesn't count on McClane and Matt figuring out what's going on. Gabriel wants McClane and Matt out of the way, and for McClane, the situation becomes personal when an enraged Gabriel kidnaps his daughter Lucy (Mary Elizabeth Winstead), who is a student at Rutgers University in New Jersey. Gabriel may think he now has the upper hand on McClane, but he has no idea how far McClane is willing to go to rescue Lucy.
Trivia: The French title translates as "Die Hard 4.0: Return to Hell". The movie's title, Live Free or Die Hard, is a reference to New Hampshire's State Motto "Live Free or Die". Consequently, the New Hampshire state film office received several phone calls asking where in the state the movie was filmed (none of the action was set on New Hampshire and focused on a little New York but mostly Washington). According to Bruce Willis and Director Len Wiseman in the DVD Commentary, the story originally involved McClane's son, Jack. Originally, he was supposed to be the computer hacker John has to deliver to the FBI. Eventually that idea was dropped and the hacker became the Matt Ferrell character. It was then decided to bring in his daughter Lucy to keep up the series continuity of McLane always having a personal stake in what happens in the story. When filming the scenes of John walking through the corridors talking to Gabriel on the two-way, there were no written lines of dialog for Bruce Willis, according to Len Wiseman on the DVD Commentary. So what they did on set was have Willis hold the two-way up to his mouth and speak gibberish so it looks like he's talking to Gabriel. If you'll notice, there are a couple of times where the two-way isn't all the way up to Willis's face and you can see his mouth doesn't match the dialog being spoken. When introduced to an agent Johnson, McClane says: "Johnson, again?". A nod to the two agents Johnson in Die Hard, despite the fact that McClane and the two agents Johnson never spoke to each other or met face to face. The name "Tovarek", which Mai Lihn (the very hot Maggie Q) uses as an FBI agent, is a Polish word and one of it meanings is "hot chick" (the correct Polish word is "towarek", but it's pronounced like this). The car that is stolen in the film by McClane and Farrell is a 2006 E60 BMW 5 series, which was chosen due to a poll that found that people wanted films that had more BMWs in it. The main reason being that the alternatives (Audis and Mercedes-Benzes) were too common and not bold and imposing enough to go with the characters in the film. The particular BMW model (5 series) was chosen because the director, Len Wiseman, found "the 3 series too common, the 7 series too uptight and every other car either too feminine or compensative for a midlife crisis.... Everything McClane isn't, yet".
When in doubt, go back to what made you a bunch of money. Recently this has been happening a bit: see Rocky Balboa, Rambo. However, this is actually a very good movie.The action is not too farfetched (well there is a little poetic license, but what do you expect, it's a Die Hard movie). You would also hope that it wouldn't be that easy to disable America now, or at least the eastern seaboard. By the way, in the Die Hard universe, what did the rest of the country go through when Washington and New York went down? I say this because the bad guys go to one of the power hubs in West Virginia (I'll talk about this later) and it seems that the guards and stuff were pretty much oblivious to what was happening 200 miles away (yeah, they guards did go to the helicopter pad and say that they couldn't land there, but you would expect someplace that vital to be surrounded with a military response if a cyber terrorist attack was in progress). Oh yeah, West Viginia. McClain and Farrell drive to Middleton, West Virginia, yep, I said drive. I checked (excpet there isn't a Middleton that I could find) the closest point in West Virginia to Washington is just under 200 miles (who knows if Middleton is right on the border or not). Now I know this is McClain's movie and he is the hero, but couldn't he get someone else to go check out the power plant instead of driving two to two and a half hours (he didn't look like he was speeding or anything)? I mean he did have a contact with the FBI a few blocks away (at this point the cell system was down). Then while he is at the power plant in West Virginia, Farrell says the Kevin Smith is in Baltimore, except he says he is "close" in Baltimore. I checked, Baltimore is also just under 200 miles away. At least this time they take the helicopter. This is why Die Hard is and always will be supperior to any reincarnation. Die Hard happened in one building, so you don't have to worry about these time issues. But out of the other three movies, this is probably the best.
