The other day I started to watch a Hungarian film and had a huge surprise.
The film is Aap (Father) 1966, directed by István Szabó
http://www.imdb.com/title/tt0060116/The very first thing you hear is M1.III, the minor-key "Frère Jacques". I was pleased to note that the film uses quite a bit of the movement, including the first, klezmer-like "trio" section. Since the opening sequences depict a young Hungarian boy's school days in 1948 I figured the intent might be to set the tone by hearing the nursery rhyme song in this darker version. The "Frère Jacques" tune returns later, in it's normal major mode. It's always a nice surprise to hear Mahler when you don't expect him
Szabó went on to direct the highly successful trilogy of films, MEPHISTO, COLONEL REDL, & HANUSSEN, among others.
An interesting film, worth checking out.
