The first trailer has landed for Happy Feet 2, the sequel to 2007′s best animated feature Oscar winner, and it has to be said, it is pretty grin inducing. As to be expected, it features a host of cute and cuddly penguins bopping about and tapping their (happy) feet, and in this case rapping to Justin Timberlake’s “Sexy Back”, albeit cunningly reworded “Fluffy Back” – think of the children! Happy Feet 2 carries some heavy weight vocal talent, including Elijah Wood, Robin Williams, Hank Azaria, Brad Pitt, Matt Damon and Sofia Vergara among a ton of others, and Mad Max‘s George Miller is returning to direct. It opens November 18, 2011 in the US, followed by a later release of December 2, 2011 in the UK. Hit the jump for the trailer and official synopsis.
