In its second weekend of release, War Inc made $19,970 at the box office, still playing on only 2 screens, for an average of $9,985 per screen.
So far after 10 days the movie has made $74,474.
Obviously since the movie is only playing at 2 theaters it is difficult to compare it to the wide releases, but the movie seems to be doing pretty well. If you go by per theater average, War Inc was #4 this weekend, behind Sex and the City, Savage Grace and Indiana Jones and the Kingdom of the Crystal Skull.
