Fox considered Brett Ratner as director (who would later direct X-Men: The Last Stand) [18] and offered the position to Robert Rodriguez, but he turned it down. [19] After the commercial success of Mortal Kombat in the United States, Paul W. S. Anderson was offered the position but turned it down, wanting to shift away from making another PG-13-rated film in favour of making an R-rated horror film, Event Horizon. [20] Following the release of The Usual Suspects, Bryan Singer was looking to do a science fiction film and Fox offered him Alien Resurrection, but producer Tom DeSanto felt he would be more appropriate for X-Men. [9] Singer was hesitant to direct a comic book film, but changed his mind after DeSanto presented the themes of prejudice in the comic that resonated with Singer. [3] Walk, Josh (August 19, 1999).
