The totals I put down were direct from Box Office Mojo (
www.boxofficemojo.com).
The amounts could be a little off - I don't work for the site - but as for
The Happening being the second highest grossing R-rated film this year, this is how the site has its list for "2008 Yearly Box Office for R-rated films"...
1.
Sex and the City $134,385,474
2.
Forgetting Sarah Marshall $62,546,460
3.
The Happening $53,196,583
These figures above are ranked by domestic totals only. By clicking on
Forgetting Sarah Marshall you'll see it grossed a total of $91,314,639 worldwide. Currently
The Happening (as I mentioned before) stands at $113,290,198 worldwide. In terms of worldwide figures,
The Happening is number 2 for the year, for R-rated films, so far.
