Several developments on a theatrical film adaptation of the "Barsoom" series emerged throughout the 20th century from various major studios and producers, with the earliest attempt dating back to the 1930s. Most of these efforts, however, ultimately stalled in development hell. In the late-2000s, Walt Disney Pictures began a concentrated effort to develop a film adaptation of Burroughs' works, after an abandoned venture by the studio in the 1980s. The project was driven by Stanton, who had pressed Disney to renew the screen rights from the Burroughs estate. Stanton became the new film's director in 2009. It was his live-action debut, as his previous directorial work for Disney was on the Pixar animated films "Finding Nemo" (2003) and "WALL-E" (2008). Filming began in November 2009, with principal photography underway in January 2010, wrapping seven months later in July 2010. Michael Giacchino, who composed many Pixar films, composed the film's musical score. Like Pixar's "Brave", the film is dedicated in the memory of Steve Jobs.
