The total, which includes the movie's stunning midnight performance, puts The Avengers behind only the final Harry Potter film, Deathly Hallows Part 2, which debuted with an unreal $91.1 million last summer.

The Avengers' $80.5 million is almost as unreal.

It's nearly $10 million bigger than the next-highest opening day: the $71.6 million posted by Twilight's New Moon.

And it's more than $13 million bigger than the opening days of both The Hunger Games, the year's biggest movie (for now?), and The Dark Knight, the biggest comic-geek thing ever (until now).

The question now is how high can The Avengers, already at about $415 million worldwide, go yet?

Can it surpass the now-perhaps modest expectations of a $150 million opening weekend? Can it go all the way past The Dark Knight ($158.4 million)? Can it go all the way past Deathly Hallows Part 2 ($169.2 million)?

Can it become the biggest thing ever, period?

At this point, it's probably best not to underestimate the Hulk.
