I never like to make absolute statements on box office, but I simply don't see where that extra 38m is coming from domestically. Even if GL, X-Men and Cap Am underperform that money isn't suddenly going to Thor.
Yeah 200M DOM is a pipe dream at this point.
But still a dream to not totally give up on, despite the stretch.
Likely analysis as I see it could go.
Memorial Day 4-day: $12m = $162m
Tue-Thur: $3m = $165
Weekend: $6m = $170/171m (X-Men First Class weekend 6/3)
Mon-Thur: $3m = $174m
Weekend: $4m = $178m (this assumes it stays under 60% drops)
Mon-Thur: $2m = $180m
Weekend: $2m = $182m (Green Lantern weekend 6/17)
Over the next 11 days I could easily see another $3m giving it
$185m going into the July 4 holiday weekend. That would be it's real last hurrah and could pull in another $3m or so then for a total of roughly
$188m after 60 days in release.
So, imo, it's not a question of where does $38m come from, it's where does $12m come from?
TIH stayed in theaters for 84 days.
Iron Man for 154 days.
Iron Man 2 for 105 days in release, leaving theaters mid August. I think Thor is much more likely to get the 100days +/- and have a real shot at "finding" that needed $12m to eek out a $200m domestic total. Thor's release and commercial success lines up with the opening and has the pull of the IM's so that means THOR would have 6 weeks to make it happen.
DVD release(bare bones?) late October/early Nov.
