According to studio estimates Sunday, the Marvel superhero narrowly bested the animated family film in a battle of sequels. "Rio 2" debuted with $39 million, almost exactly the opening weekend total of the 2011 Oscar-nominated original.
Two other new releases opened in a distant third and fourth place.
The low-budget supernatural horror film "Oculus" took in $12 million. The football drama "Draft Day" debuted with $9.8 million. Starring Kevin Costner, "Draft Day" was made with the co-operation of the National Football League.
