If you loved The Birds, try Frenzy
A bridge between a film you've already seen and one most people haven't. Frenzy has roughly 4.4× fewer votes than The Birds — 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 Alfred Hitchcock, and they sit in Horror / Thriller territory. If that's the register that drew you to The Birds, the second film will land in a comparable space — through a different lens.
What Frenzy is
London streets at dusk, a Bowler hat lies abandoned. A brutal murder unfolds, a suspect emerges, a desperate chase begins. Hitchcock tackles the darker side of human nature with characteristic flair.
