Mercury Rising is a very conventional "government bad guys" story about evil agents out to kill an autistic boy who can break their top code. Of course, the premise of the movie, that the government would rather kill someone who can break their code rather than fixing the problems with the code, is incredibly stupid. If one boy can break the code, isn't is reasonable that some other boy in Russia or wherever can also break it? If it has a flaw that allows the kid to find the pattern, doesn't it need to be fixed? Of course, not. We just kill the kid and pretend nothing ever happened.
But, what is really sad is that there is a grain of truth in this story. It is the policy of the US Government that TRYING to break codes is illegal. If you are smart enough to figure out that the DVD encryption has a major flaw, it's not the fault of the designers, it's your fault. Researchers who have discovered flaws in codes, watermarks, etc, have been arrested. This "head in the sand" policy has been around for a long time.
So, next time you see this movie, just think how easy it would be to combine this attitude with someone a bit too gung ho.
