When I was around 10 to 15 years old, I really loved the musicals. As I recall, the film that kick-started the whole thing was Chitty Chitty Bang Bang, which was shown in a local film theater when I was 10.
When you think about it, the way some memories are associated with a particular period of life is strange. I vividly recall that I was exactly a 5th grader when I saw the film in the darkness of my favorite film theater.
As one gets older, memories are not so well designated to a specific period. For example, it is sometimes difficult to temporally pin down the initial viewing of some memorable films (e.g. Solaris, El Sur, L'Albero degli zoccoli) that I encountered in my 20s. The childhood days are marked by vivid and colorful progressions of time. As one passes adolescence, the segmentation of time becomes less clear.
Back to Chitty Chitty Bang Bang. There were some features of the film that captured my imagination. For example, the contraptions that the mad inventor father (played by Dick van Dyke) builds in the film fascinated me. One of them cooked an egg and made a sandwich at the breakfast table, with some disastrous results.
There were some lovely tunes, like "Doll on a Music Box", where Truly Scrumptious (played by Sally Ann Howes), pretending to be a mechanically constructed doll, dances on a music box, ostensibly presented as a special gift to the tyrant Baron Bomburst.
There is a clip of this beautiful scene on youtube.
Looking back, the whole film is lovely, as in it the adults endeavor to entertain the children and children-at-hearts very seriously.
