In an interview for NPR, director Paul Thomas Anderson shares his experience adapting Thomas Pynchon’s Inherent Vice for the big screen:
I approached it in the most straightforward but laborious way I could come up with. I transcribed the dialogue… And there were multiple times when I thought, “Why don’t I just call the publisher and get a PDF and cut and paste this on the computer?” But there was something about typing it out again that made me — it made me get to know the book, you know, really deeply.
