unproduced. Another two of their earliest scripts which were never produced were Plastic Man, based on the DC Comics superhero of the same name and Vertical Run based on the book of the same name by Joseph R. Garber. After completing The Matrix, the Wachowskis were looking to make an animated adaptation of Frank Miller's Hard Boiled graphic novel. The comic was drawn by Geof Darrow, the conceptional designer of The Matrix and later its sequels. The project didn't move forward because Miller didn't want it to be an animated film.
