Ilya and Alexander Salkind continue to bring the lore and legend behind the World's Greatest Super Hero to the big screen in this follow-up to the beloved Christopher Reeve Superman films. Helen Slater (in her screen debut) stars as the sensational Supergirl! Though Superman grew up believing himself to be the Last Son of Krypton, part of his home planet survived: Argo City, home of his uncle, Zor-EI (Simon Ward), and Zor-EI's wife, Alura (Mia Farrow). Saved by the wizardry of Zaltar (Peter O'Toole) and the Omegahedron, their daughter Kara comes of age as a Kryptonian when a disaster whisks the Omegahedron to her cousin's adoptive planet, Earth. Dispatched to rescue it from the clutches of the evil sorceress Selena (Faye Dunaway), Kara must tackle a steep learning curve so that she can pass the test as both mild-mannered schoolgirl Linda Lee and Supergirl!
