Jason Bourne is at it again. He still doesn't know who he is but luckily he still knows how to kick some serious behind. The Bourne Supremacy is the sequel to 2002's Bourne Identity. Both are based on the highly successful Bourne novels by Robert Ludlum.

Supremacy picks up three years after Identity left off. Marie (Franka Potente) and Jason (Matt Damon) are still together and still trying to stay one step ahead of the people who are still out to get them. If constantly running and hiding weren't bad enough, Bourne has been implicated in a failed CIA mission and the agency, led by Pamela Landy (Joan Allen) thinks that he is responsible for the murders of two operatives in the process.

Director Paul Greengrass piles on the action with several high intensity car chases. Bourne is on the run for most of the movie and the movie does a good job in keeping up with his frantic pace.

While the action was straight forward and unrelenting, the same could not be said of the plot. I was able to follow it okay but several audience members did complain that it was hard to follow. The twists and double-crosses add to the intricacy of the plot but if it's so intricate that it's confusing then there is a problem.

As far as performances, the movie really belongs to Damon with an assist from Joan Allen. Damon is intense, calm and anguished all at once. Allen is exactly the tough cookie that one would expect as a woman who has risen through the ranks of the CIA's boys club. The other characters only purpose is to move Bourne and the plot along. Julia Stiles, as Nikki, who worked with Bourne when he was with the Agency and Brian Cox, as Ward Abbott, who led the secret program that trained Bourne are very generic roles that could have gone to just about any actor.

But no one is going to the Bourne Supremacy to see Julia Stiles or Joan Allen, for that matter. People are going to see this movie because it is an action-packed, popcorn thriller. And that it is.
