If you loved if...., try O Lucky Man!
A bridge between a film you've already seen and one most people haven't. O Lucky Man! has roughly 3.6× fewer votes than if.... — 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 Lindsay Anderson, and they sit in Drama territory. If that's the register that drew you to if...., the second film will land in a comparable space — through a different lens.
What O Lucky Man! is
