The filmmakers cited the series' first installment, The Curse of the Black Pearl (2003), as inspiration for the script and tone of the film. Pre-production for the film started shortly before On Stranger Tides was released in early 2011, with Terry Rossio writing the initial script. In early 2013, Jeff Nathanson was hired to write a new script for the film, with Depp being involved in Nathanson's writing process. Initially planned for a 2015 release, the film was delayed to 2016 and then to 2017, after 6 years of development hell, due to script and budget issues. Principal photography started in Australia in February 2015, after the Australian government offered Disney $20 million in tax incentives, and ended in July 2015.
