David Dunn (Willis) is your typical guy. He has a wife, though a troubled marriage, and son and a stable job as a security guard for a local college. On his train-ride back from an interview in New York, his train derails and everyone except him dies; in fact, he doesn't have a scratch on him. At first, Dunn doesn't know what to make of this event and assumes it is some strange twist of fate. It isn't until he leaves the mass service of the people that died on the train and finds a note under his windshield wiper asking him to try and remember the last time he was sick, that he starts to realize that there might be something different about him.
After talking with various people and looking back at his life, he can't remember ever being sick. He and his son travel to the establishment that the note came from, a place called Limited Edition. Limited Edition is an art gallery that specializes in comic book art and artists. The shop owner is a man named Elijah Price (Jackson), who suffers from a genetic disorder that leaves his bones extremely brittle and easy to break. Throughout his life, he has had to be careful because the slightest bump could lead to incredible pain and hospitalization.
At some point in Price's life, he realized that he sat at one extreme of human abilities, and that there must be someone out there who is his opposite, someone whose bones don't break, who doesn't get sick. He believes that these people who are stronger than your average person are the basis for the mythologies portrayed in comic books, and he has been watching the news for some sign of a person that might exhibit the abilities he is looking for.
So when Jackson hears that a sole survivor has walked out of the wreckage of a derailed train with no injuries whatsoever, he feels like he might have finally found his hero. Of course, both parties are skeptical; David and his son aren't sure what to make of this theory (though the kid really is quick to believe), and Price wants to be certain that his find is real. In their discussion, we learn that David once played college football, but because of an accident, he couldn't play anymore. But this is also where Price learns that David is a security guard and believes that his decision to go into a job of protection is a good sign.
A majority of the movie is dialogue as Price's faith in Dunn's identity wavers and gets renewed, while he keeps pressing David that he is more than just a normal person. Meanwhile, David and his wife attempt to rebuild their marriage, and their son wrestles with his own realization of his dad's abilities. All of the character development in this movie is just great, and the lead up to David's first truly heroic act, and the following twist (in a true Shymalanian manner) are just great, but if you haven't seen the movie before, then I don't want to ruin it.
As far as special features are concerned, there doesn't seem to be anything above what was included on the 2-disc DVD set that came out a few years back, but it still has a good bit of good stuff including deleted scenes and a couple of featurettes concerning comic books and the making of Unbreakable.
Both comic book fans and M. Night Shyamalan fans alike will find this release to be a good addition to your Blu-ray collection, and if you haven't seen the movie already, then it is definitely worth a rental at the very least.
