The family audience that made 'Hop' the top movie of the last two weeks finally went south. To Brazil.

The macaws of 'Rio' can crow over the year's biggest opening weekend so far, debuting with an estimated $40 million. Belated horror sequel 'Scream 4,' which some experts thought would give 'Rio' a run for its money, settled for about half as much, premiering with an estimated $19.3 million.
