Good movie, much of it filmed in and around New Orleans.

Rating: Null/10 (22 May 2007)

As a former resident of the famous Crescent City, I must admit that much of my enjoyment watching this movie came from the recognition of familiar scenes. Even some of the areas devastated by storm Katrina in 2005 were featured within the context of the story.
Denzel Washington stars as agent Doug Carlin who comes in to help investigate what appears to be a terrorist attack, an explosion which sinks a Mississippi River ferry full of military on Mardi Gras leave. The story relies on a technology that doesn't exist and in fact probably should be considered impossible, warping time and space to be able to interact with the recent past.
I enjoyed the movie, it held my attention and the production values are first-rate.
SPOILERS FOLLOW. Jim Caviezel is antagonist Carroll Oerstadt, the disgruntled man who is responsible for the explosion. One of his victims is Paula Patton as Claire Kuchever, but her body washes onshore a few minutes before the explosion occurred. Carlin (pronounced 'car-LEEN') quickly figures out, from clues under a bridge and from security video, that the same person murdered Kuchever also sank the ferry. Fortunately a secret government project allowed them to see 4 days into the past, in real time, and are able to observe the victim's last hours and identify the killer. The big leap of faith happens when Carlin puts himself into the machine and goes back 4 days to prevent her death and the explosion. Mandatory action on the ferry near the end, shootings etc.
