Imagine the elevator pitch: an eight-hour psychological thriller set in 1960s Italy, filmed in black-and-white and starring Fleabag’s Hot Priest as an amoral killer whose crimes are witnessed by a cat? From this unlikely premise, writer-director Steven Zaillian (The Night Of) has fashioned Ripley, an entertaining and meticulous drama starring Andrew Scott as the grifter’s grifter: Tom Ripley. Now streaming on Netflix, it’s every bit the cinematic spectacle, despite its small-screen home.
