A hit man takes a vacation and finds both danger and faulty workmanship follow him wherever he goes in this offbeat comedy from Thai filmmaker Pen-ek Ratanaruang. Kyoji (Asano Tadanobu) is a hired killer based in Macau who works for Japanese crime boss Wiwat (Toon Hiranyasup). Kyoji poses as a chef to maintain his cover, and he gets to put both skills to use when Wiwat asks him to kill his wife Seiko (Tomono Kuga) with a poisoned meal, not a difficult thing to arrange since Kyoji has been having an affair with her for several months. After dispatching Seiko, Wiwat thinks Kyoji could use a little R&R, and sends him on a cruise to Phuket. However, Kyoji discovers he's been given a cut-rate stateroom in which anything that can go wrong does on a regular basis. However, this turns out to be the least of his troubled when he discovers he's being trailed by two mysterious figures -- an attractive single mother who may or may not be flirting with him (Gang Hye Jung) and a large man in a Hawaiian shirt (Mitsuishi Ken) whose motives are difficult to ascertain. Invisible Waves received its North American premier at the 2006 Toronto Film Festival. ~ Mark Deming, All Movie Guide
