By July 2009, Scott was attached to direct the film, and screenwriter Jon Spaihts was hired to pen the script based on his pitched idea for a direct Alien prequel.[40][60] With both director and writer in place, and pleased with Spaihts's pitch, Fox scheduled a release date for December 2011, but this was eventually dropped.[61] In June 2010, Scott announced that the script was complete and that pre-production would begin, with a filming date set for January 2011.[62] However, by July 2010, Lindelof had been hired to redevelop Spaihts's screenplay into a more original work.[63][64] In October 2010, Lindelof submitted his refined screenplay to Fox. The studio was pleased because it had contested Scott's proposed budget of $150–160 million and found Lindelof's screenplay to be more budget-conscious;[citation needed] Scott had initially requested a $250 million budget and an adult oriented product, but Fox was reluctant to invest this amount of money, and wanted to ensure the film would receive a lower age-rating to broaden the potential audience.[65]
