Writer-director Paul Haggis sets up this film with a nice slow build. The whole time you're watching you can feel the tension inching its way into your seat.
Then, in one gripping freeway scene the movie suddenly shifts into full speed ahead as the action plays out.
Crowe gets extra points for often having to convey what's going on without ever saying a word--acting with props instead of people.
And it's great to see Elizabeth Banks - who's so well known for her comedy work - get back into the drama world. Her range is evident and impressive.
This is a smart movie and it's fun to watch what happens as you guess along the way.
