Consequence of Sound’s oral history of the movie High Fidelity (via Dan Barrett) notes that the television series, ostensibly based on the book, is cribbing hard from the movie without acknowledging it.
DEVINCENTIS: The TV show was supposedly an adaptation of the book, not an adaptation of the movie — that’s what the credits say. Yet, there were entire scenes, concepts, shots, and dialogue lifted directly from the movie — again not from the book — without any credit or attribution. Like, even an Easter egg in-joke I laid in to a record store scene for a friend — the meaning of which the TV writers could never know — was simply lifted and dropped into their teleplay with the rest of it.
