Back in the early 2000s, DC Comics and Warner Bros. was trying to get a new Batman movie off of the ground, and one of the ideas they were looking at was Batman Vs. Superman. This is the script that was written for the film by Andrew Kevin Walker (Sleepy Hollow) and Akvia Goldsman (A Beautiful Mind), and you can read the full thing below if you want to see what they were planning. I seriously doubt any of this will make it into the upcoming movie, but ya never know!
