I know how difficult it is to lose a loved one, but the most painful thing is to lose your own son or daughter. This is actually a good kidnap movie with some good thrills and heartbreaking moments. I also found it interesting how the police in this is so inferior in just about every way possible that it gets very freaking annoying, in fact I hated the police in this especially that fat women police person than the kidnapper himself. Although I am sure a lot of the stuff that happens in this movie is made up to keep the audience entertained, it's based on a kidnapping that took place in Korea. Where they never caught the kidnapper and the only trace they have is a recorded message left on the phone. There is a lot of what if moments in this movie, where you think what if things went differently a lot of times or if the characters made a slight different decision. Sol Kyung-gu also proves why he is one of the top actors in Korea, his performance made the final act even more heartbreaking and sad. The negative aspect is that this becomes a linear cat and mouse game, and the cat and mouse game aspect of it wasn't intriguing enough.7.8/10

This is easily the best kidnapping movie that has ever been made. If you have yet to embrace Korean cinema, you are missing out on some of the best films to hit the screen. Kyung-gu Sol is one of the best actors on the planet, if you don't believe that go watch "Oasis", "Rikidozan" or any of the "Public Enemy" movies. This movie may be his greatest performance, the emotional highs and lows is character goes through are just amazing to watch. I can't believe the NY Times gave this movie a bad review, saying "Voice of a Murderer is an uninvolving melodrama more suited to the small screen than to the large.", I would love to know what movie they were watching. This is a masterpiece that more people need to see!!

This film was very intense. Although it was not violent or graphic, it had many psychologically intense and stressful scenes. And it offers a real glimpse of life in Seoul; the relentless traffic, endless high rise apartments and the fast-paced life of the urban sprawl. As a parent, I could really empathize with the characters. Because it was based on a true story, the whole event takes on more gravity. Unlike many other recent child-kidnapping movies, i.e. with Denzil Washington, or Mel Gibson's Ransom, this "The Voice of a Murderer" is not a Hollywood movie. There are no heroes. It has a fresh take on a familiar plot, with very believable characters.

I doubt very much whether this film will be released in the UK in the near future as we sadly have a very high profile child abduction case in the news at the moment. However, this film is extraordinary. Based on a true-life (unsolved)case from 1991, Han Kyung Bae (Sol Kyung Gu) plays a successful, yet ruthless news anchor with a beautiful wife (Kim Nam Joo) and a nine-year-old son. But suddenly his successful life comes crashing down when his son gets kidnapped. In the next 44 days, the parents continuously receive calls from the kidnapper with instructions and requests for ransom. The police are determined to find the kidnapper, but he effortlessly eludes capture; not only is he a step ahead at every turn, he seems to enjoy toying with the police in this cat-and-mouse chase. As the kidnapper keeps walking free, Kyung Bae becomes increasingly desperate and frustrated with the police, as he knows time is running out for his child. This is an uncomfortable subject but the acting from the two leads is quite astonishing. And given the title of the movie, we know the outcome of the case from the start. But that doesn't detract from the grip the film has on the viewer. Not surprisingly, this film has been the highest grossing Korean film of 2007 to date. And wait for the end credits to hear the actual voice of the murderer. That's really chilling.
