According to ERC Box Office, Avatar has earned an estimated $27 million on its opening day in various formats including 3D IMAX. At this rate, the film is poised to become the third highest grossing film in history for the month of December.

Avatar is estimated to take in $74 million over the course of its first three days in release. That wouldn't quite have it breaking the best December opening weekend, which is currently held by I Am Legend. Will Smith's film debuted with $77 million on its opening weekend this same time two years ago.
