In the climax, John Carter (Taylor Kitsch) battles Matai Shang (Mark Strong) and the Therns, a mysterious and manipulative race. The Therns have been sowing discord on Mars, and Carter discovers their true intentions. With the help of his allies, including the Thark leader Tars Tarkas (Willem Dafoe) and the Heliumite Princess Dejah Thoris (Lynn Collins), Carter confronts the Therns to save Barsoom.
In the resolution, Carter successfully thwarts the Therns’ plans and brings about a resolution to the conflicts on Mars. The film ends with Carter bidding farewell to Dejah Thoris, expressing his intention to return to Earth. However, he is determined to find a way back to Mars and be with the woman he loves.
The ending sets the stage for potential sequels, with Carter’s ongoing adventures on Mars and the possibility of further exploration of the planet’s diverse civilizations.
“John Carter” faced challenges at the box office and received mixed reviews, but it has gained a cult following for its imaginative world-building and action sequences. The ending leaves room for additional stories in the Barsoom series, though no sequels were produced.
