Finally I saw this film on a college campus viewing in 1969 and tried to have a discussion about it with a stranger....big mistake. This is no light-weight film.

But consider the pace of the film, each second of life was dear and sweet, the music gave focus to the sunlight. She was beautiful in youth (the worshiped idol of the 60's and on). He was caught in his love for her, a grasp at life as with the one you love, trapped in the amber of film, forever.
The young couple were living without a plan for the future, not unusual when you're young. Their natural vitality gave a calm pleasure to each segment of dialog free film. A snippet of life savored. One wonders: Is old age our souls' goal?
Yes the audience is practical, steal a chicken, flee the country, do something. And if so how is their love and beauty made to stand before us? Tragedy is necessary.
Now, I'm much older, but still, once every so often I will see an Elvira walk by, I hold my breath and marvel and am pleased that the world still has room for more such Elviras. Grace and beauty.
Since that time, with the perspective from the artists' work I can see a world that would have been only guessed by me, perhaps in a dream; thanks to Elvira Madigan.
