You do a cross-comp of the budget through the above site, in 2010 dollars Fox spent no more that $78.7 Million, which is still pretty cheap compared with a few stated film budgets for some pics.

Consider that IRON MAN's budget in 2008 was reported as $140 Million, THOR's last year was $150 Million, and GREEN LANTERN was stated to be $200 Million, you realize just what a bargain Fox got. And you further look at their genre films for last year, with RISE OF THE PLANET OF THE APES coming in at $93 Million and X MEN: FIRST CLASS between $140 Million and $160 Million, you see some serious environmental changes in how films are done between then and now.

Which means that when someone says they don't make SF films like they used to, they can prove that with a spreadsheet...
