In "Revenge of the Sith", set three years later, Obi-Wan is now a Jedi Master and a member of the Jedi Council, as well as a General in the Grand Army of the Republic. Anakin, by now a Jedi Knight, remains Obi-Wan's partner, and the two have become war heroes and best friends. The film opens with the two on a rescue mission to save the kidnapped Supreme Chancellor Palpatine (Ian McDiarmid) from cyborg Separatist commander General Grievous (Matthew Wood) on board his cruiser. Dooku duels the Jedi once again, knocking Obi-Wan unconscious; while Obi-Wan is out cold, Anakin defeats Dooku and executes him on Palpatine's orders. Soon after returning to Coruscant, Obi-Wan travels to planet Utapau to track down Grievous.
