You guys should Google box office fraud sometime, both domestic and foreign.
To expand on that...
While “deep throat” was “porno chic” and did send suburbanites to the porno theater, it also provided a convenient way for organized crime to launder money claiming that millions were coming in at the boxoffice (thy owned theaters). They didn’t even use ticket stubs at one point, opting to use those metal clickers to tally sales (click-click-click, “write it down”).
pinball machines, jukeboxes, washiterias, etc. were another way to launder receipts...
I do not doubt some fraud takes place....it does in nearly every industry. But fraud will not take a $100 million movie and make it a $1 billion movie.
