Query: For a movie that takes place mostly in 1 room, it's really intense.

A nuclear expert turned Islamic extremist has planted bombs in very populated areas. The FBI has picked him up and sent their top "interrogator" to put the screws to him. The relationship developed between the 2 men and another FBI agent grows stronger and stranger. At the same time, time is running out for the bomb clock. To save the lives of many Americans, the unthinkable will happen.This movie is extremely intense. Especially considering that most of it takes place in a single room. The torture is graphic, and the drama is very heavy. This is one of the finest roles I have seem Samuel Jackson play. The same goes for Michael Sheen. They are both amazing, and make a great duo. This movie also makes you think about what kind of things happen to ensure our freedom. Freedom that most of us probably take for granted. If you can handle very heavy subject matter, this is a powerful and thought provoking movie. I highly recommend it.
