Terrible acting, screenplay and direction.

A movie that not only functions as a solid scarefest but a razor-sharp satire.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

Sometimes when diving through the DVD bargain bin, you can find a gem of a movie. Other times you can find movies that while they are not great, are all the same good enough to be worth the small cost you have to pay. "I Witness" is one example of the latter. It seems to have been a labor of love for all concerned, given the obvious low budget. Actually, the small budget does not really hurt the movie, since the majority of the movie takes place in run down Mexican locations; without a big budget to spruce things up, you can really feel the poverty and the breeding place for crime and corruption. The cast does a pretty good job, especially James Spader, who really shines despite having a somewhat limited part. Jeff Daniels is also good, though his character seems at times to be somewhat naive for someone who has made a career going to various hot spots around the globe looking for human rights violations. If there is any other flaw with the script, it's that the story unfolds at a somewhat slow pace (though the movie never gets boring.) It's a good movie that's worth seeing. One warning, though: If you are thinking of travelling to Mexico for any purpose, by the end of the movie you'll probably be cancelling your plans.

In Tijuana, dozens of innocent people are murdered, and the police are bent on blaming the local drug cartel. A human rights activist, played by Jeff Daniels, originally sent to monitor a union vote at an American-owned company, begins investigating the murders. He soon learns that the drug lord is a harmless, lovable fuzzball trying to earn an honest living. Meanwhile, the American company, trying to keep their business from becoming unionized, ends up at the center of the investigation in typical Hollywood sucker-punch style.Yes, it's an interesting plot, but Hollywood is really good at inserting its Anti-American bias into an otherwise perfectly good modern murder mystery.

A very hairy Jeff Daniels and James Spader costar in a baffling murder mystery down Mexico way. Daniels is a human rights observer and Spader is an American cop assigned to a dusty Mexican border town. Dozens of bodies are found in a collapsed tunnel, and the question becomes why were they in the tunnel in the first place? An Amercan company operating in town may hold the answers, but the answers will prove to be hard to comprehend and possibly fatal for the finder, as a Mexican detective assigned to the case keeps reminding Daniels. Excellent acting, a convoluted mystery, and a sense of foreboding that is right out of some classic '80s thriller like AGAINST ALL ODDS. Someone also compared this STV to TRAFFIC. A fair comparison. A must-see for mystery fans.

I've read other comments here which say it's also like "Traffic." Ditto that for me as well. Don't know who these writers are (Colin Greene and Robert Ozn) but they are truly awesome. Tight plotting, terse cop-talk tied to characterization and impassioned issue oriented story-line without preaching. Love the way the writers tie the diverse story lines together at the very end. I never guessed how it was all related and they really knew how to keep me hooked. Jeff Daniels gives a very cool,understated performance. Love Portia DeRossi, very sexy without trying. And of course James Spader is always fascinating to watch - wish he had more to do in this flick. I saw this in Europe on a DVD. How come this thing is not out in the USA?!
