A taut (if somewhat run-of-the-mill) Argentine film noir. Positives: good script and cinematography, excellent acting from all concerned especially the protagonist, Julio De Grazia. Negatives: an obtrusive and frequently strident score (many scenes would benefit from an absence of music).
This is the first film by Argentine director Adolfo Aristarain, who went on to direct some of the best Argentine movies of the last three decades, among them "Time for Revenge" (1981), "A Place in the World" (1992), "Common Ground" (2002) and "Roma" (2004). In the light of these works "The Lion's Share" must be considered as a minor work, but it is worth watching.
