Brave earned $66.7 million dollars to take the number one spot in its opening weekend. Madagascar 3 dropped to number two, making the top two weekend films both animated!

The family-friendly Madagascar 3: Europe's Most Wanted barely edged out the sci-fi horror film Prometheus for first place in the weekend box office. Meanwhile, the Avengers showed up in the top five for the seventh straight weekend.

Prometheus and Madagascar 3 are off to equally strong starts in the weekend box offices. These two competing films got us wondering about who might win between other interesting historical pairs.
