Happy Feet Two is a 2011 CGI-animated jukebox musical comedy film directed, produced and co-written by George Miller. It is the sequel to the 2006 film Happy Feet. Elijah Wood, Robin Williams, Hugo Weaving, Magda Szubanski and Anthony LaPaglia reprise their roles from the first film, with Common and Alecia Moore (P!nk) replacing Fat Joe and Brittany Murphy (who died two years before the film release) respectively, and with Hank Azaria, Brad Pitt, Matt Damon, Sofia Vergara, Richard Carter, and Ava Acres joining the cast. In the film, young penguin Erik, who is reluctant to dance, runs away from home and encounters the Mighty Sven, a tufted puffin. When the penguins are trapped by a giant wall of ice and snow, they must save Antarctica.

An international co-production between the United States and Australia, Sydney production houses Kennedy Miller Mitchell and Dr. D Studios produced the film, which premiered in North American theaters on November 18, 2011, and in Australia on December 26, 2011. The film received mixed reviews, with critics praising its animation, music and voice acting, but criticizing its story. The film underperformed at the box office, grossing $150.4 million against its $135 million budget. This resulted in the closure of Miller's Dr. D Studios, making this their only animated film.
