In 2005, Joseph Kozinski wrote the 12-page story "Landscape of Lost Wars" five years before directing the first feature feature film "Genesis: War History". Kozinski had always dreamed of writing "Lands of Lost Wars" into a screenplay. Later, he met Barry Levine and Jesse Berg, the founders of Radical Films, and they adapted the story together into a picture book novel by Alvid Nelson. Written, drawn by Andre Warin, and directed by Kozinski, Barry Levine, and Art Director Jerome Berg of Radical Films. Later, it also won the support of fans at the 2010 San Diego International Comic Con, when the Radical Film Company booth issued a total of 30,000 volumes of picture book novels in the exhibition.
The day after the comic show, director Coggins and Tom Cruise decided to sign a contract based on the picture book novel. It took nearly a year to write the script. Kozinski was first able to collaborate with William Monaghan, and then Karl Gedusek and Michael Amt also participated. Universal Studios also began to develop this case with Kozinski, Radical Films, and Scherney Entertainment. Peter Scherney, the producer of "Rise of the Apes", also joined the film.
For the film, Kozinski and Barry Levin recruited several producers to join, including Dylan Clark, who worked with Scherney on "Rise of the Planet of the Apes", as well as "Furious Sea" and "Harry Duncan Hudson, producer of "Potter and the Philosopher's Stone". After locking Karl Gedusek and Michael Amter as screenwriters, the production team finally started this project to shoot the movie version of "Lands of Lost Wars". The design team recruited important members of the original "Creation: War History" to jointly create the post-apocalyptic world.
In September 2010, before the release of "Genesis: Legend of War", Disney hired the screenwriter William Monaghan of "Infernal Walker" and "Kings of Heaven" to adapt the script for the movie version. The Disney company had already done a lot of preparatory work for the shooting of "Lands of Lost Wars", but ended the production of the film in early 2011. Universal Pictures, which took over the film project of "Fallen Lands" from Disney, set aside a $100 million production budget for the film and invited screenwriter Karlrewrite William Monaghan’s script.
