 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".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".The themes of prejudice in the comic resonated with Singer.
