Some see crazy, we see sheer talent. And crazy. Because if you’d look closely at this Don Corleone portrait, from Coppola’s The Godfather, you’ll see that the entire image is made of the movie’s completely handwritten (all words legible) screenplay.
Detail. You can pick out some of the film’s famous lines.
Wow, as you said, crazy (in a good way) and talent really do describe that work perfectly! It’s impressive!
