I first saw this on TV in about 1990, before i had heard of either Colin Firth or Ken Branagh. I was astonished at the quality performances both gave, but for me, particularly Firth's. I was not at all surprised that both became very successful and famous later, though it took Firth longer to rise to the limelight than Branagh, something which initially irked me (but only a little!).
But back to the film! Wonderful, evocative, very moving, and with an excellent soundtrack. It portrays the hardships of life in 1920, not just the fallout from terrible war, but also the then-incurable illness (TB). Thanks to the reviewer who identified the location; i plan to visit the church / valley for a walk / picnic some time this summer. And - trivia - the actor who played Old Birkin (David Garth) died the year after this movie was made (1988). It was his final appearance, and it made me weep.
And the unrequited love between Firth and Richardson beats hands down so many cheesier scenes of fully-requited "love" in more "popular" movies. And therefore meant so much more ...
What a film.
