Sequel to Tim Burton's hugely successful 'Batman' (1989). Oswald Cobblepot was abandoned by his parents as a baby. Thirty three years later, bent on revenge, he returns to Gotham City as the Penguin (Danny DeVito). First he begins a warped campaign to become Mayor, helped by millionaire businessman Max Shreck (Christopher Walken); next, he undertakes a mission to murder every first born son in Gotham - a plan which will avenge his own beginnings. Meanwhile, he has two adversaries to contend with: Catwoman (Michelle Pfeiffer), the embittered ex-secretary of Max Shreck, and, of course, the old caped crusader himself - Batman (Michael Keaton).

When Martians arrive on planet Earth, American President James Dale (Jack Nicholson) is persuaded to extend the hand of friendship. One of the President's advisers, Donald Kessler (Pierce Brosnan), has been studying the aliens, and is keen to make peaceful contact. However, the Martians gleefully fry their greeting party from Earth, and launch an all-out attack on the planet. Various celebrity faces including Michael J. Fox, Danny DeVito and Martin Short appear briefly before being zapped by the Martian baddies in director Tim Burton's quirky spoof of alien invasion movies.
