The author of the book is Walter Ruggle. On the sleeve, it says he was born in Switzerland in 1955, is a film critic, and also writes for the Swiss film magazine "filmbulettin" (a decent magazine, which I read from time to time). He is also supposed to have written "larger works" (an awkward translation) on Bunuel, Greenaway, Kurosawa, Leone, Marker, Mizoguchi, Pasolini, Rohmer, Tarkovsky, and others. If they are anything like this 300+ Angelopoulos book, I'd love to get my hands on them.

I also tend to avoid reading about films I'm not familiar with in recent times. Don't know why exactly - maybe I'm subconsciously hoping to get hold of all those films in the near future?
