John Lithgow plays Roald Dahl not as the whimsical creator we grew up with, but as a brilliant, towering antagonist who spent a single, explosive afternoon in 1983 nearly blowing up his own legacy over a single book review. It’s the kind of high-stakes, dialogue-heavy drama that makes you realize how thin the line is between a creative genius and a neighborhood bully, especially when the person holding the pen refuses to apologize for what they've said.
