A more complete (though written, not film) history is the article at wikipedia.

I think the period of roughly 01700–01950 in which Portugal, Britain, and The East India Trading Company (EIC) played a large role is more interesting because of the strong influence of opium and countries and corporations other than China on China’s history, with perhaps the Century of Humiliation or 百年耻辱 (01839–01949) being the most interesting.
