Films about Composers

Occasionally I get asked if there is a film about a particular composer. There are a lot of feature films and TV documentaries and I have just built a page on my 52composers website on the subject.
The two British directors Ken Russell and Tony Palmer have been prolific with this genre.
Some, notably those by Tony Palmer, are incredibly well researched and true to the facts. Others have varying proportions of fantasy.
Yale University has published a book 'Composers in the Movies' by Prof.John C.Tibbetts and with a forward by Simon Callow. I haven't seen it yet but it looks interesting.
