The Fellowship of the Ring went on to break the December opening weekend record as well with $47,211,490 -- generating $75,129,468 in its first five days. If The Two Towers were to follow the same pattern, that $26 million would point to a $67 million weekend. However, being a sequel with even more rabid fandom than the first, it's likely more frontloaded. Perhaps a closer analog would be The Phantom Menace. Its Wednesday start led to a $64.8 million weekend. A comparable trajectory would give The Two Towers $59 million for the weekend and $97 million after 5 days.
New Line will not be releasing actual numbers for The Two Towers until Friday (for Wednesday and Thursday). The reason is that there are some inconsistencies that they're trying to reconcile.
Keep going that way TTT.
