Absolutely, I had to read Don Quixote when I heard about the difficulties Terry Gilliam has faced to bring his vision of it to film. It also just happened to be a hilarious must-read classic, which, I actually didn't know much about before watching the documentary Lost in La Mancha (2002). Don Quixote is one of the first widely popular novels written in shorthand, making it a fairly straightforward read compared to a lot of the other great novels written in the 17th century. The story behind it being brought to film is just as quixotic as the tale itself.
