What is the fine-grained topic of the following text: I've had the pleasure of working with many of the best modern film music composers: Hans Zimmer (BBC's Emmy Award Nominated "Planet Earth II" & "Blue Planet II"), Max Richter ("Guerrilla"), Ilan Eshkeri (“Informer”) Harry Gregson-Williams ("The Town"), Benji Merrison (“BBC Earth: Dynasties”, “General Magic”), Murray Gold ("Doctor Who"), Zbigniew Preisner ("The Beautiful Country"), Paul Englishby ("The Musketeers"). Only return the topic.
