 The world version of the film received much more praise than the US and Canada version.The film opened briefly at #1, grossing $2,466,530 from 1,206 theaters on opening day; an excellent number in documentary standards, despite being far from the opening day total of its predecessor, "Earth".However, the film was overshadowed by its competition with "The Back-Up Plan" and "The Losers" as well as continued success from "How to Train Your Dragon" and "Date Night".
