I believe the budget was much less...

Also cant forget the infamous Hollywood accounting, you know the money they spent fucking with the Gambit movie was slipped into the budget of this somehow, same thing happened to MOS & Superman Returns which inflated the budget on both of those movies quite a bit iirc, that and paying that weird producer who demanded a robot spider and is adamant the sword goon from the 89 Batman made that movie $100m for that one scene, movies are so bloody odd.
