If you loved Iris, try Notes on a Scandal
A bridge between a film you've already seen and one most people haven't. 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 Richard Eyre, and they sit in Drama / Romance territory. If that's the register that drew you to Iris, the second film will land in a comparable space — through a different lens.
What Notes on a Scandal is
