By November 2013, 20th Century Fox had begun negotiations for the treatment for a third Wolverine solo film with director James Mangold and Donner attached to produce. Mangold said that it would be inspired by other Wolverine stories from the comic books and it would be made after "X-Men: Apocalypse". In March 2014, David James Kelly was hired to write the script. In April 2015, Michael Green was hired to work on the film's script. Principal photography commenced in May 2016 in New Orleans, Louisiana, and concluded in August 2016. The film was released on March 3, 2017, and marked both Hugh Jackman and Patrick Stewart's final run as Wolverine and Xavier, respectively.
