With something like 110 feature films under his belt, Takashi Miike is the first that comes to mind for me. Even just in the “family” comedy genre , the range between happiness of the katikuris and visitor Q is astonishing. The former is actually close to family friendly (with the exception of one shot Iirc) and the latter is one of the most OTT-taboo-laden and shocking movies of all time —and both are hilarious. Of course he is most known for shock value and stylized violence, but the restraint and patience of the first 2/3 of Audition is unparalleled and truly makes the last act hit harder than anything I’ve ever seen. Taking the time to develop the characters and story makes all the difference, although much of the credit there belongs to the author of the novel, Ryu Murakami. Still, it is a really faithful and wonderful adaptation.
I’m not even sure of another director with as many films, let alone as much range. Looking over to the west, Scorsese comes to mind. There is a pretty chasm between Hugo and Casino. Lynch too (between the elephant man and, say, lost highway).
I love seeing artists broadening their horizons and flexing their skills by demonstrating versatility. I’d also love to hear any other examples you all may share, thank you :)
