Actually it has made as much as STFC did when accounting for inflation....in just over a WEEK!
RAMA
First Contact made US$146m.
As it stands ST:ID has only made US$67.2m thus far.
Nemesis made US$67.3m.
So in straight figures it hasn't beaten either of those films yet. True the Sunday figures for the US+Canda and the first full week for the rest of the world (where it was relased on May 9)have yet to come in which should easily push it past First Contact figures.
Accounting for inflation, STFC made over $164 million. Through Sunday STID will make $158 million minimum. It now seems like the figure will be closer to $165 million. So in basically a week, STID has made MORE than the most popular STNG film in its whole run even with the higher inflation figure. I used it as an example since Nemesis was a poor analogy.
Edit: The Numbers already has STID listed at $84,091,000 domestic $164,591,000 Worldwide. The Intl numbers were revised from $75 million to $80.5 million.
So despite the panic, STID probably will do $5 million more domestically in fewer theaters, for 5 days.
