There are two things we know about James Cameron: he can"t be rushed, and he loves the ocean. Those qualities come together in Avatar 2, the first of a whopping four planned sequels to his 2009 spectacle, the highest-grossing movie of all time. The new film returns to the planet of Pandora, where blue-skinned Neytiri (Zoe Saldana) and her human husband Jake (Sam Worthington) are now parents, and Earthlings still haven"t solved the climate crisis. Most of the action takes place underwater and was shot in a 900,000-gallon tank. The Avatar sequels have been in the works for a decade, but Cameron"s water-logged hits, Titanic and The Abyss, also arrived behind schedule, and it all turned out just fine. (CJ)
