I'm so grateful he was able to make Twin Peaks: The Return before he passed. It's one of the most brilliant and moving pieces of fiction I've ever experienced. If they had started it just a few years later it may have never been finished.
Some of the people who returned for it died not long after it wrapped. The "Log Lady" might have died before it wrapped, even, can't recall. Miguel Ferrer wasn't around much longer. Even with Lynch living a good while past it, it'd have been far more limited production if it'd started even a couple years after it did. They already had to do without Bowie and a few others that it seems Lynch might have liked to use (given what he did with the season), like Frank Silva (BOB) of course, and notably Don Davis (Major Garland Briggs).
