The great countercultural novelist Rudolph Wurlitzer has talked of writing a Buddhist thriller in which the action gets progressively slower. There’s some of that in this movie, Thai maestro Pen-ek Ratanaruang’s fifth feature, which moves from Macao to Thailand. Though this time the director doesn’t take a script credit, he returns to the genre basics of his first two films, Fun Bar Karaoke (1997) and 6ixtynin9 (1999), to give us a moody, philosophically downbeat, cryptically stylish thriller about a Japanese hit man (Tadanobu Asano) assigned to kill his own lover (and his boss’s girlfriend). The lush cinematography is by the great Christopher Doyle. In English and subtitled Thai, Japanese, and Korean. 115 min. (JR)
