In the 9th weekend of release, War Inc made $12,200 at the box office playing on 20 screens (the same amount of screens as last weekend). War Inc hit a wall this weekend. It dropped 59.6% from last weekend which is substantial compared to the past few weekends when it only dropped about 20% each time. The per theater average was hovering around $1,500 the past few weeks dropped to $610 this weekend. War Inc has made a total of $541,284 at the box office.
There's no telling how much of an effect The Dark Knight had on War Inc. I suppose there is quite a bit of crossover audience for those two movies. With "Batmania" going on at movie theaters all over the country few people were probably looking forward to seeing indie pics.
