One thing you will see mentioned in every review of the Irishman is Martin Scorcese’s use of de-aging technology to make his stars appear several decades younger as part of the film’s meditation on time, loss, and regret, and there is no covering up the fact that the digital effect occasionally turns its actors into disconcerting goblins. Their faces smooth out like cutscenes from a next-generation video game system. They maintain their elderly physiques so that Robert De Niro plays a mob hitman whose method of assassitation involves briskly walking at people, and Al Pacino’s Jimmy Hoffa retains the hunched posture of a near-octogenarian even as a middle-aged man; Pacino also goes through a closet of ludicrous wigs as specified by his contract.
