The original title of this Flemish police proceduralThe Alzheimer Caserefers to the fact that its vengeful hit man, like the hero of Memento, suffers from periodic bouts of amnesia and struggles to plan his moves in relation to them. This may sound gimmicky, but director Erik Van Looy skillfully profiles both the assassin (Jan Decleir, suggesting a tougher, over-the-hill version of Michel Piccoli) and the Antwerp detectives investigating his crimes. Van Looy and Carl Joos adapted a novel by Jef Geeraerts to produce this violent, sleazy story (2003). In Dutch and French with subtitles. R, 120 min. (JR)
