To get the filler out of the way:  Cage plays MIT professor John Koestler.  His son opens a time capsule and gets a “drawing” of a weird series of numbers.  John discovers that the numbers all refer to major world catastrophes.  There are three dates left.  What will happen on those dates?  What will happen on the last one?  

        Again, the best parts are the action sequences.  There are five sequences that the film will be remembered for.  Three of them involve crashes of various modes of transportation.  One is a dream sequence.  The last is the one that makes for the film’s climax.  All five sequences are amazing, but the finale is truly breathtaking.  I won’t tell you what it involves, except that only the fact that you’re still alive will convince you that it is only a movie.      

        Horror movies are a dime a dozen, but “Knowing” is the first movie I’ve seen in a long time that is truly terrifying.   The action sequences are disturbing in their intensity and the sense of hopelessness they instill.  The rest of “Knowing” isn’t very memorable, but I defy you to forget the film’s most powerful moments.
