Filming was to start in early 2003, with plans for a five- to six-month shoot. The release date was set for the summer of 2004. However, Warner Bros. canceled development to focus on individual Superman and Batman projects after Abrams submitted another draft for "Superman: Flyby". According to Petersen "Bros.' chief Alan Horn was so torn, because it's such a fascinating concept to do a Batman versus Superman film". Horn reportedly preferred Abrams' optimistic Superman script to the darker "Batman vs. Superman" script; studio executives voted 11-1 for the former. Many comic book fans agreed; David S. Goyer said, "'Batman Vs. Superman' is where you go when you admit to yourself that you’ve exhausted all possibilities ... somewhat of an admission that this franchise is on its last gasp". Since the decision left the studio without a Batman film for 2004, Warner quickly made "Catwoman", which performed poorly at the box office.
