I'll admit I laughed when I first heard about this film. It's a sort of Significant Issues Gumbo: Nazi war criminals and the Israeli-Palestinian conflict and the acceptance of homosexuality all feature in it together, elbowing one another aside for the limelight.
So much for mixed metaphors. The film is about Eyal (Ashkenazi), a Mossad agent whose task it is to find a now-elderly Nazi war criminal. He poses as a tour guide for the man's grandson, Axel (Berger), who has come to Israel to visit his sister (and also to cruise the gay bars).
Walk on Water raises some interesting and important issues around accountability and reconciliation. The film does very well given what it's grappling with, and manages to be thought-provoking without being heavy-handed.
