The Amazing Spider-Man 2 isn't putting up the spectacular numbers Sony (SONY -0.71%) Pictures executives were hoping to see.

Box Office Mojo reports that The Amazing Spider-Man 2 earned an estimated $37.2 million is U.S. theaters over the weekend, upping its domestic haul to $147.9 million overall. Worldwide, the Spidey sequel has grossed $550.9 million to date. A good figure, to be sure, but also a far cry from what its predecessor earned in a less competitive summer movie season. Catching up won't be easy.

Two monsters of the cinema are coming your way soon: Legendary's Godzilla on May 16 and Michael Fassbender as the mutant malcontent Magneto in X-Men: Days of Future Past on May 23. Credits: Twenty-First Century Fox and Legendary Pictures.

A big bet that isn't paying off ... yet
How bad is it for Sony? I've got some figures comparing The Amazing Spider-Man and The Amazing Spider-Man 2 in the table below. Before we get to that, it's worth noting that the studio has bet on much more than a $250 million sequel.

"We are expanding the Spider-Man universe into The Sinister Six and Venom, so that we have Spider-Man movies every year," Sony Pictures Entertainment co-chair Amy Pascal said in March.

That won't be easy to pull off, especially if the Wall Crawler's newer movies can't deliver as well as Sam Raimi's trilogy from a decade ago. The Amazing Spider-Man still ranks as the lowest grosser in franchise history, and it still may outperform The Amazing Spider-Man 2. Have a look at the scorecard:

A web of profits still likely
Where does this leave Sony investors? Probably wondering if Pascal's franchise ambitions are as realistic as they seemed only a few months ago.

My guess is nothing has changed. Even if The Amazing Spider-Man 2 fails to match its predecessor's $752 million in worldwide grosses, the film is still likely to be box office profitable by the end of its run. Mix in DVD, Blu-ray, and digital sales and the numbers start to look even better.

So even if Spidey gets stomped when Godzilla enters theaters -- and then promptly forgotten when X-Men: Days of Future Past shows up a week later -- chances are the Wall Crawler and his enemies are still well positioned to bring years of profits to Sony shareholders.
