X-Men: The Last Stand is a 2006 American superhero film directed by Brett Ratner, the third installment in the original X-Men trilogy. The film follows two parallel storylines: Jean Grey returns from her apparent death with vastly amplified, unstable powers as the Dark Phoenix, and the U.S. government develops a "mutant cure" derived from a young mutant's ability to suppress the X-gene, forcing mutants to choose between accepting the cure and fighting to preserve their identity. Magneto assembles an army to destroy the cure's source, while the X-Men must stop both Magneto and the increasingly dangerous Phoenix.

The Last Stand was the most commercially successful X-Men film at the time, earning $459 million worldwide, but was critically divisive and remains one of the most debated entries in the franchise. Brett Ratner replaced Bryan Singer, who departed to direct Superman Returns, and many felt the film lacked Singer's thematic depth and character nuance. The film made the controversial decision to kill several major characters including Cyclops and Professor Xavier, choices that felt rushed to many fans.

The Phoenix storyline, one of the most beloved sagas in comic book history, was criticized for being subordinated to the cure plotline rather than receiving the development it deserved. Despite these issues, the Golden Gate Bridge sequence and Wolverine's emotional confrontation with Jean Grey provided memorable moments.
