Though box office grosses are based on ticket sales information collected by independent organizations, the published numbers are typically self-reported by film distributors and thus should not be trusted as 100% reliable. Movie budget information is almost always self-reported and estimated and may or may not include the costs of distribution and marketing and other ancillary costs. Movie studios may report a very small budget for a big hit to make it look like they made "something out of nothing" or may report a very large budget for a very lavish super-production (or large budget numbers may be leaked and reported by others in order to mock a flop). The general point here is that financial statistics in the movie business should always be considered more as signifiers of power in the industry and less as objective measurements.
