Barely beating Madagascar 3's $20.5M, Prometheus won Friday's box office with an exciting $21.4M!

And we're not entirely surprised...

But just because they edged out the animals on opening night doesn't mean they're gonna win the war!

In fact, experts predict M3 to make buzz, with CNN praising it as "spectacular!"

With Michael Fassypants Fassbender and Charlize Theron starring, it should be!

Which one did U see last night??
