Mumble grows into an adult (voiced by Elijah Wood), still half-covered in fluffy down. Mumble’s class graduates, and although he has not graduated, he joins them on their first trip into the ocean. His class ends their day by partying on an iceberg. Mumble constantly interrupts their singing and is forced to enjoy the party on a small iceberg. Mumble dozes off and wakes to find himself alone. A leopard seal chases him off the iceberg, and the penguin finds himself far from his home. He finds some Adelie Penguins, small in stature, but fiercely loyal to those they call friends. He befriends a small group of bachelors who form a club called “the Amigos”: the leader Ramon, the brothers Raul and Nestor, and twin brothers Rinaldo and Lombardo. The Amigos quickly embrace Mumble’s dance moves and assimilate him into their misfit group. Mumble’s joy is cut short when he accidentally starts an avalanche and causes a hidden human excavator to tumble out from a glacier. Driven by curiosity, he sets out to find the “aliens” responsible for the machine. Mumble has a lot of questions, and the group suggests that he ask Lovelace (a Rockhopper or Macaroni Crested Penguin) who answers questions in exchange for stones and is known as the guru, as well as being the leader of the Adelie penguins. Lovelace has the plastic rings of a six pack entangled around his neck, which he uses to project his guru image. When asked if the rings were from the aliens, Lovelace denies that aliens exists and claims that the plastic rings were bestowed upon him by mystic beings.

In Mumble’s old home, it is mating season, and Gloria (voiced by Brittany Murphy) is the center of attention. Although she is surrounded by a large horde of suitors, none of their heartsongs interest her. Ramon tries to help Mumble by singing a Spanish version of “My Way”. Gloria is not fooled, however, for she knows Mumble cannot sing. She notices Ramon behind Mumble and shoves him away to reveal the little penguin. Gloria becomes angry and turns her back on Mumble. As Mumble has no heartsong, Gloria continues towards the other males visibly distraught. As a last resort, Mumble tries to persuade her to sing along to his tapping rhythm. Because of her affection for him, she complies. As Mumble’s beat speeds up, Gloria finds the chorus to her heartsong, and realizes it is “Boogie Wonderland”. Overcome with happiness that they can now be mates, the pair begin dancing, along with the other penguins.

Noah the elder sees their lack of fish as punishment from the Great ‘Guin for Mumble’s dancing. Mumble tries to explain about the mysterious “aliens”, and that they are the cause of the scarceness of fish, but only his mother and Gloria believe him. Noah exiles Mumble from the colony. Mumble vows that he will find the real cause of the famine. Mumble and the Amigos return to Lovelace only to find him being choked by the plastic rings. Lovelace confesses that he got stuck in the rings while swimming near the forbidden shores. He reveals that the forbidden shores are located past the land of elephant seals and beyond the blizzard country. Mumble, the Amigos and Lovelace start their journey. Gloria tries to come, but Mumble, fearing for her safety, drives her off by insulting her singing talents. They travel across vast territories till they reach the shore.

Mumble sees a boat and swims after it, leaving his friends behind. He swims far from the usual hunting range of Emperor Penguins and ends up washed up exhausted on a warm shore. He is rescued and kept for a while in a penguin exhibit at a marine park named Marine World. He tries to communicate with the “aliens” that surround him. When his pleas fail, Mumble nearly succumbs to madness after three months of confinement. Mumble starts dancing, and soon a large crowd gathers around the exhibit. He is released back into the wild, now with more adult feathers, and a tracking device strapped to his back. He leads the humans to his native colony. The other penguins are skeptical at first, but when Gloria notices the tracking device, they realize that the “aliens” exist. Now convinced, the penguins (along with the once-stubborn elders) dance alongside Mumble in hopes of getting the humans’ attention.

A research team arrives and film the penguins dancing. They bring this footage back to the human world, and a worldwide debate ensues. The world governments realize they are overfishing the Antarctic waters, and conclude that the penguins are trying to communicate that to them. Antarctic fishing is banned, and the fish population recovers. At this, the Emperor Penguins and the Amigos dance and celebrate their triumph. A dancing baby penguin seen at the end is implied to be the child of Mumble and Gloria.

In the end credits, the characters reunite to dance for the final number, “The Song of the Heart.”

The world rejoices at Superman’s return, but he has difficulty coping with Lois’ fiance, Richard White (James Marsden), nephew of Daily Planet editor-in-chief Perry White (Frank Langella), and their 5-year-old son, Jason (Tristan Lake Leabu). With Superman distracted by an out-of-control vehicle (a diversion involving Luthor’s henchwoman, Kitty Kowalski), Luthor steals Kryptonite from the Metropolis Museum of Natural History. Perry then assigns Lois to interview Superman while Clark investigates the blackout. Lois and Jason inadvertently board Luthor’s ship and are captured after Lois decides to hold interest in the blackout story, which she connects to Luthor’s experiment. He reveals to them his grand scheme of using one of the stolen Kryptonian crystals, which he has combined with the Kryptonite, to grow a new continental landmass in the Northern Atlantic Ocean that will cause sea levels to rise drastically, killing billions of people.

Seeing Jason seemingly have a slight reaction to Kryptonite, Luthor asks who Jason’s father really is; Lois asserts that the father is Richard. The crystal begins to create Luthor’s new landmass, while Lois attempts to escape but is attacked by a henchman. Jason throws a piano at the henchman, killing him and showing that he is actually Superman’s son. Meanwhile, Superman is attempting to minimize the destruction in Metropolis caused by the new landmass’ growth when Richard arrives in a sea plane to rescue Lois and Jason. Superman soon arrives to help and then flies off to find Luthor.

Meeting Luthor, Superman discovers the landmass is filled with Kryptonite, which weakens him to the point that Luthor and his henchmen are able to beat him. Superman is stabbed by Luthor with a shard of Kryptonite and falls into the ocean. Lois makes Richard turn back to rescue Superman, whereupon she removes the Kryptonite from his back. Superman, after regaining his strength from the sun, lifts the landmass after putting layers of earth between him and the Kryptonite. Luthor and Kitty escape in their helicopter; Kitty, unwilling to let billions of people die, tosses away the crystals that Lex stole from the Fortress of Solitude. She and Luthor are stranded on a desert island when their helicopter runs out of fuel. Superman pushes the landmass into space, but is weakened by the Kryptonite and crashes back to Earth. Doctors remove more Kryptonite from Superman’s wound, but after it is removed they cannot penetrate his skin with their surgical tools. While Superman remains in a coma, Lois and Jason visit him at the hospital where Lois whispers a secret into Superman’s ear and then kisses him. Superman later awakens and flies to visit Jason, reciting his father Jor-El’s (Marlon Brando) last speech to Jason as he sleeps. Lois starts writing another article, titled “Why the World Needs Superman”. Superman reassures her that he is now back to stay, and flies off to low orbit, where he gazes down at the world once again.

Hong Kong circa 1973. Lee, a member of a Shaolin Temple, is a master of the physical and spiritual disciplines of the martial arts, and is being visited by Braithwaite, a British law officer. Lee has been invited to a tri-annual martial arts tournament held on an island owned by Han, a reclusive billionaire who was once a member of the Temple but has now become a renegade.

Braithwaite believes Han uses his tournaments as cover for narcotic and prostitution activities. Lee reluctantly agrees to enter the tournament, but his reluctance to confront Han disappears when a Shaolin monk reveals that during the previous staging of this tournament, he and Lee’s sister were accosted by several toughs led by Han’s personal bodyguard, an American named O’Hara. In the ensuing confrontation the monk cut a deep scar on O’Hara’s face but Lee’s sister ultimately perished, and at her gravesite Lee vowes revenge for her death.

Also attending the tournament are two American martial arts experts, John Roper and Kelly Williams, who served together in Vietnam and took differing paths toward martial arts upon their discharge – Roper is on the run from Mafia gambling debt collectors, while Williams was accosted by two racist cops whom he’d dispatched before stealing their car to escape. All three will soon find themselves at the mercy of Han and his army of martial arts fighters as he protects his underground factory of narcotics and prostitution.
