Film fans head for 'Rio' with $40M debut

Movie fans are going to "Rio" in big numbers, but they're not quite screaming over the latest installment of a horror-comedy franchise.

Anne Hathaway and Jesse Eisenberg's animated family flick "Rio" led the weekend box office with a healthy $40 million debut, according to studio estimates Sunday.

But the slasher comedy "Scream 4" opened at No. 2 with just $19.3 million, a fraction of the business for the previous two sequels, which both debuted at over $30 million more than a decade ago.

After two weekends in the No. 1 spot, Russell Brand's Easter bunny tale "Hop" slipped to third-place with $11.2 million, raising its total to $82.6 million.
