Another film purported to have been the highest-grosser is the 1972 pornographic film "Deep Throat". In 1984, Linda Lovelace testified to a United States Senate Judiciary Subcommittee on juvenile justice that the film had earned $600 million; this figure has been the subject of much speculation, since if it is accurate then the film would have made more money than "Star Wars", and finished the 1970s as the highest-grossing film. The main argument against this figure is that it simply did not have a wide enough release to sustain the sort of sums that would be required for it to ultimately gross this amount. Exact figures are not known, but testimony in a federal trial in 1976—about four years into the film's release—showed the film had grossed over $25 million. Roger Ebert has reasoned it possibly did earn as much as $600 million on paper, since mobsters owned most of the adult movie theaters during this period and would launder income from drugs and prostitution through them, so probably inflated the box office receipts for the film.
