Prior to the release of Batman Begins a few years ago, Frank Miller penned a screenplay based on his graphic novel 'Batman Year One'. The screenplay (which also borrows from his graphic novel 'The Dark Knight Returns') was submitted to Warner Bros but was rejected as being too violent.
However, this original script was leaked onto the internet for all to read! If you have the time, I urge you to read it, whether or not you are a fan of the comic. In my opinion this would have been a better film than Batman Begins (although I did like it). It's a gritty, brooding, violent street-level script which is just as much about Bruce Wayne as Commissioner Gordon. Take a look:
