Bloody hell, I enjoyed it but I didn't think it would make anywhere near that.
Superhero movies usually seem to make between 200 and 500.
It's probably an exception as this was the first superhero movie where everyone, I mean EVERYONE enjoyed. From my young cousins to old working colleagues bringing their Grandkids to watch, coming out saying how brilliant it was.
Keep it up and I'm sure the sequal will make it big too.

6 of the top 38 are superhero movies, all well over 500m in takings.
Iron Man 1 and 2 made over 500m, as did the random Hancock.
The rest, as you both say, are rather poor in comparison. Thor appears under 500m, Batman just over 400m.
Crazy that those have done so well, especially Spiderman3!!
