Unknown

There are a few more unknown movies named Unknown. A big, more known Unknown was Liam Neeson's 2011 movie which is I think is better known than this 2006 one. Liam Neeson's Unknown was good but in my opinion this one was more gripping, and slightly more believable and better and had a better twist in the end. Although both are a bit out there as far as the plot is concerned, this is more gripping. 

This Unknown is truly a locked room mystery. Limited location, budget and characters. 

It begins with 5 people waking up in a warehouse and not remembering anything about who they are or how they got there. All they know is they are trapped, there is no way to communicate with the outside world, except for a phone that rings occasionally with instructions for one of them, because there is a killer amongst them!

To remain alive they have to find out who they are, what they are doing there, and who amongst them is the criminal and who is victim.

So they begin to talk and work out things, and as they explore their surroundings and find out more about each other, they realize they are in terrible danger because someone is coming there for them. They have to work out who is bad and who is good and they don't have all the time in the world. 

Gripping stuff all of this, although it may require you to suspend disbelief a bit. Just go with what is happening and enjoy the ride as long as it lasts.

And by the way, there are a few twists in the end! Completely unexpected. It impressed some people in Bollywood so much that they totally ripped it off and made a terrible carbon copy of the film - Acid Factory. But if the copy is all messed up, blame the copier and not the original? Right? Because if it's being copied, then it must be good. And I believe it was. Check it out for yourself.
