Five men wake up one by one in a locked warehouse. None of them can remember who they are or how they got there. The first to wake up is Jean Jacket (Jim Caviezel). As he looks around he sees a guy with a broken nose (Greg Kinnear), one tied to a chair (Joe Pantoliano), one handcuffed to a rail in obviously very hurt (Jeremy Sisto) and one apparently simply passed out (Barry Pepper). While everybody else is still out cold, Jean Jacket wanders around and receives a phone call through which he fakes his way through. But it is obvious that something shifty is going on and Jean Jacket and everybody else have to figure out what it is and what side they’re on.
I started this movie under the impression that I hadn’t seen it before, but about five minutes in I realized that I had, actually. I couldn’t remember practically anything about it, though – it’s that kind of a movie.
Martin Harris (Liam Neeson) travels with his wife Elizabeth (January Jones) to Germany to attend a conference. While Elizabeth checks into the hotel, Martin ends up in a car accident. Cab driver Gina (Diane Kruger) saves his life, but Martin ends up in the hospital in a coma. When he wakes up after four days, he barely remembers anything. Slowly his memories return, but when Martin tries to find Elizabeth it is only to find himself replaced with another Martin Harris (Aidan Quinn) and Elizabeth not knowing him.
Unknown is exactly what it promises to be: a rather mindless action flick with a convoluted story and very mixed performances. It entertains, but not much more. Nothing less, either.
