Clash of the Titans is a 2010 action fantasy film and remake of the 1981 film of the same name produced by Metro-Goldwyn-Mayer (the rights to which had been acquired by Warner Bros. in 1996 through its purchase of Turner). The story is very loosely based on the Greek myth of Perseus. An international co-production between the United States, United Kingdom, and Australia, the film is directed by Louis Leterrier from a screenplay by Travis Beacham, Phil Hay, and Matt Manfredi, and stars Sam Worthington, Gemma Arterton, Mads Mikkelsen, Alexa Davalos, Ralph Fiennes, and Liam Neeson. The film was originally set for standard release on March 26, 2010, but it was later announced that the film would be converted to 3D and was released on April 2, 2010.

Clash of the Titans was a commercial success, grossing $493.2 million worldwide and becoming one of the highest-grossing films of 2010, but received generally negative reviews from critics, with praise for its epic scale, visual style and the performances of Neeson, Fiennes and Arterton, but criticism for Leterrier's direction, Worthington's performance and the post-production 3D conversion. The film's success led to a sequel, Wrath of the Titans, released in March 2012.

Plot During the gods' battle against the Titans, Hades created the Kraken, a fearsome monster that helped win the gods' victory. Zeus and his brothers then divided the world amongst themselves: Zeus took the skies, Poseidon the seas, and Hades, deceived by Zeus, was left to rule the Underworld.

Zeus later created the mortal humans, whose worship maintained the gods' immortality. Over time, however, some mortals began to defy their creators. When the human king Acrisius leads a siege at Mount Olympus, Zeus has sex with his wife Danae, conceiving a demigod son, Perseus. Upon discovering this, an enraged Acrisius locks the queen and her newborn child in a chest and throws them into the sea. Zeus retaliates by striking the king with a lightning bolt, which severely deforms him. Perseus and the now-dead Danae are found by the fisherman Spyros, who raises the baby with his wife Marmara.

Eighteen years later, Perseus and his family watch as soldiers from the city of Argos destroy the statue of Zeus, declaring war on the gods. The soldiers are slaughtered by the Furies, who are controlled by Hades. Hades then destroys the family's fishing vessel; Spyros and his family drown, with Perseus as the only survivor.

Found by another group of soldiers, Perseus is brought before King Kepheus and Queen Cassiopeia, who are celebrating their campaign against the gods. While their daughter Princess Andromeda disapproves of her parents' rebellion, Cassiopeia furthers her boasts. The revelry is suddenly interrupted by Hades. He kills Cassiopeia by rapidly aging her, threatens to unleash the Kraken upon Argos in ten days unless Andromeda is offered to it as a sacrifice, and reveals Perseus's godly heritage. Perseus meets Io, a mysterious woman cursed with immortality, who confirms his origin.

Perseus, Io, and the King's Guard led by Draco journey to the Stygian Witches, seeking a way to defeat the Kraken. To help his son, Zeus tries to give Perseus a sword forged on Olympus, which he refuses. Soon after, they are attacked by the corrupted Acrisius, now known as Calibos, who is working for Hades. During the fight, Draco severs Calibos' hand, forcing him to retreat to a desert where the blood from his injury conjures giant scorpions which attack the group. They are rescued by a band of djinn, desert sorcerers who tame the remaining scorpions and lend their aid to Perseus and his group.

They arrive at the lair of the Stygian Witches, who are forced to reveal a weapon to defeat the Kraken: the head of the gorgon Medusa, who resides in the Underworld. Upon arrival, Perseus and his remaining companions enter Medusa's temple lair, while Io remains outside. Medusa kills everyone except Perseus, who finally manages to behead her by using the reflective underside of his shield to see her with his back turned. As they are leaving Medusa's lair, Calibos appears and fatally stabs Io. As Perseus and Calibos fight, Perseus picks up the Olympian sword and kills his opponent; Calibos' human form is briefly restored, and he begs Perseus not to become like the gods before he dies. As Io lies dying, she urges Perseus to save Andromeda and Argos.

The winged horse Pegasus arrives and takes Perseus back to Argos while Hades, having manipulated Zeus and the gods into earning their trust, releases the Kraken. Prokopion, a fanatical worshipper of Hades, and his followers take Andromeda to be sacrificed. Perseus arrives in time and exposes Medusa's head to the Kraken, which gradually petrifies and crumbles. Prokopion attempts to kill Perseus, but Kepheus intervenes, and both of them are then crushed by the Kraken's falling claw. Hades confronts Perseus, but the latter, invoking Zeus, hurls his sword at Hades, forcing him back to the Underworld.

Perseus rescues Andromeda, who asks him to rule Argos by her side as king, but he declines. Later Zeus appears before Perseus and offers to bring him to Olympus which he also refuses. Zeus, while disgruntled, accepts Perseus' choice and revives Io allowing them to be together.

Alternative ending After defeating the Kraken and Hades, Andromeda falls into the sea and Perseus dives in to save her. When he reaches her, he embraces her with a passionate kiss, indicating that they have fallen in love. After reaching the shore and regaining consciousness, Perseus tells Andromeda that he will return. Getting on Pegasus, he flies to Mount Olympus and confronts Zeus, stating that he does not wish to be one of them. After slamming his sword into the gods' map and shattering the models of every living person, he flies on Pegasus over the sea, presumably back to Argos.

Production

The Clash of the Titans remake project started in 2002 under producer Adam Schroeder and writers John Glenn and Travis Wright. They wanted to drop the "cheesy chessboard manipulation of characters" by the gods. Wright and Glenn described their story as "an adventure film with religious elements". Producer Basil Iwanyk revived the project in 2006 with a rewrite by Travis Beacham, a fan of the original, who intended the script to be "darker and more realistic". Lawrence Kasdan and director Stephen Norrington signed on in 2007. Kasdan gave the script another rewrite from the Beacham version. But Norrington was unsure about his direction for the project because he did not grow up with the original. Leterrier, who did, contacted Norrington through their shared agent about replacing him. By June 2008 Leterrier joined the project and Warner Bros. greenlit the film. Leterrier noted the original Clash of the Titans inspired the climax of his previous film The Incredible Hulk – a battle in a burnt-down courtroom with temple-like columns – and has compared modern superheroes to Greek mythology.Louis Leterrier and Tim Roth's audio commentary for The Incredible Hulk, 2008 DVD by Universal Studios Home Entertainment

Writers Phil Hay and Matt Manfredi took over the script during July 2008 and used Beacham's draft as a starting point. They focused on the mythology and telling the story through Leterrier's eyes. Hay and Manfredi had to rewrite the script in less than a year using a very active process. Leterrier sought Ray Harryhausen's involvement. He also reunited with Hulk concept artist Aaron Sims, who had already been working on Clash of the Titans with Norrington.

Louis Leterrier, during an interview, revealed that he is a big fan of Masami Kurumada's Saint Seiya manga (also known as Knights of the Zodiac) and its anime adaptation. He specifically cited the armor that the Gods wear in his film remake as a sign of homage and respect to Saint Seiya. Masami Kurumada, the author of Saint Seiya, was even asked to collaborate with the production team on poster designs.

Sam Worthington did not wear sandals while filming; he instead painted toes on his sports shoes so he could perform the stunts better.

According to actress Emma Thompson, she almost made an accidental uncredited cameo in the film while visiting her friend Liam Neeson on the set. Thompson, who had been filming Nanny McPhee and the Big Bang in an adjacent studio, went to visit Neeson during a break, just as Neeson was about to shoot a scene with Ralph Fiennes and Danny Huston. Unable to exit the set fast enough as the cameras began to roll, Thompson, in her clumsy Nanny McPhee costume, had to hide behind Huston's throne during the take so she would not be picked up by the cameras.
