A quick Google search doesn't produce any proof, but it's hard to believe that this classic Swedish coming-of-age story didn't partly inspire Bergman's Sommaren med Monica
, generally acclaimed as one of the most brilliant films of his early period. There's no girl, but many other elements are the same. The three boys steal a yacht and sail out to spend the summer cruising the Stockholm archipelago; after a while, food stocks run low and things begin to fall apart.
If you're a fan of the movie, you may well want to check this one out. While I like Bergman's version better, Siwertz has his own take on the idea and there are some extremely good scenes. Just as with the Bergman, it simultaneously manages to be idyllic and very disquieting.
Well, we've now seen the 1987 movie version, and I'm afraid it's rather disappointing. Most of the key scenes are there; the story's soul, however, has disappeared. The result is a cute teen adventure rather than a glimpse of the abyss lying behind the world's sunny facade.
Oddly enough, Sommaren med Monica
is more like the book than the movie which is supposed to represent it. I'm reminded of Brazil
