Attack of the Clones (Star Wars: Episode II)
The Separatist movement, the attempted assassination of Padmé Amidala (Natalie Portman) and the Clone army are all elements of Chancellor Palpatine's (aka Darth Sidious, played by Ian McDiarmid) plot to overthrow the Galactic Republic. Jar Jar Binks (voice of Ahmet Best) is used as the patsy to set in motion the inevitable slide towards the evil Empire.
