Bryan was trained by Snake before he left Outer Heaven to join the CIA.This Would Explain A Lot.
It's all an extreme case of Even Evil Has Loved Ones.An Alternative Character Interpretation I've thought of...What we're given of Bryan's past, and indeed some of how he acts now that It's Personal, could easily indicate that he is, if not necessarily a Retired Monster, at least someone who could easily have been the villain of another story in his younger years.
Jean-Claude will factor in the sequelSomewhat implausible, but maybe the guy is forced to work with the albanians or something.
Bryan Mills is secretly HannibalObviously, Taken takes place during a temporary retirement, and after the whole mess with rescuing his daughter, he went back to his old job after realizing that it's what he was meant to do.
Bryan is not finished yet...We have no clues that Bryan stopped killing human traffickers at the end of the movie. It's perfectly possible that, after he's spent some time with his beloved daughter, he'll just get back to business and kill the rest of the organization. After all, they know to much, and they weren't exactly nice towards his daughter, so he has a good reason to finish them off. And when the streets of Paris are drenched in the blood of the traffickers that were foolish enough to think they cound handle a war against hells most prolific servant, he'll leave the terrified city and declare another war on all the criminals of the United States. And then, he'll meet Frank Castle. It won't take long for them to kill every single criminal in the world, and soon, hell will freeze and the darkness itself will whisper the name of every single grieving mother they have created, and the laughter of the dark gods will be silenced when they gaze into the eyes of Bryan and Castle. The world will never be the same again... and all of this because some asshole thought it would be hilarious to kidnap Bryans daughter! Thank you, fucker!
Liam Neeson's character in Unknown is BryanCome on, he's a super badass assassin spy kicking ass in a major European capital, only this time with amnesia. His line "I didn't forget everything, I know how to kill you, asshole" is pure Bryan.
That guy tied to the chair is not dead...You remember that guy who was tied to a chair and tortured by Bryan? At the end of the scene, Bryan turns on the switch one last time before leaving the room, letting the poor guy burn. You know what I think? I think he's still sitting on that god damn chair!
In the inevitable Taken 3, the kidnapped party will be...Kim and Jamie's young daughter. (Played, inevitably, by Claire Geare.)
Jamie is one of Murad's last two sons.He is living in America to receive a Western Education so that he'll grow up to handle the family's more legitimate business interests. As of the end of Taken 2, he knows now that Bryan is the man who killed his father and brother.
Bryan will team up with The Expendables in Taken 3Because who better to bring with you to put down the sex traders so hard that they can never possibly recover? Besides, it would be awesome.
Bryan Mills is Darkman.It all makes sense! Why else would a 50+ year old man have the speed, stamina, and endurance of a man half his age? It's all the adrenaline pumping through his veins 24/7. Sometime between Darkman 3 and Taken, the US government discovered Dr. Westlake's activities. In exchange for his services to the country (and no jail time), they helped Westlake perfect his synthetic skin formula. The US government had a super soldier on their hands and renamed him Bryan Mills. He uses different aliases during the movie so it's obvious Mills is just another cover name. Eventually, he is allowed to retire from his service and this brings us to the present day. This also explains Mills' recklessness and ruthlessness to get to his daughter, because Darkman can get batshit crazy when he's messed with.
Bryan Mills is an AssassinNot only does he have the know-how and combat skills of an Assassin, sans the hidden blades, but he's also has their type of climbing abilities and the scene where he mentally reconstructs how Kim was taken was reminiscent of investigations that Connor conducted, meaning that he probably has eagle vision.
