If you loved Doodlebug, try Quay
A bridge between a film you've already seen and one most people haven't. Quay has roughly 7.1× fewer votes than Doodlebug — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Christopher Nolan. If that's the register that drew you to Doodlebug, the second film will land in a comparable space — through a different lens.
What Quay is
Eraserhead if it were a DVD extra. Nolan spotlights Stephen and Timothy Quay, the stop-motion animators behind uncanny shorts and music videos. A peek into their workshop reveals the source of their unsettling genius.
