If you loved I Know Where I'm Going!, try The Life and Death of Colonel Blimp
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 Emeric Pressburger, Michael Powell, and they both carry the bittersweet, tender mood tags, and they sit in Comedy / Drama / Romance territory. If that's the register that drew you to I Know Where I'm Going!, the second film will land in a comparable space — through a different lens.

What The Life and Death of Colonel Blimp is
A film that perhaps believes in the romance of war a little too much. It follows the career of a British officer via flashbacks, from the Boer War to World War II, with emphasis on his friendships and love affairs. It's certainly a long life.
