With corrosive wit and rigorously precise technique, this mesmerizing new film from director David Fincher (The Social Network, NYFF48; Gone Girl, NYFF52) pares the payback thriller down to its spare but deeply pleasurable essentials. Adapted by Andrew Kevin Walker from a graphic novel by Alexis “Matz” Nolent and Luc Jacamon, and starring a perfectly chilled Michael Fassbender as a globe-trotting hit man of near-ascetic commitment to his craft, it’s an exemplary process movie in which revenge proves unpredictable, character is action (and inaction), and murder isn’t personal — until, suddenly, it is. A Netflix release.
