The Amateurs (2005)

Revealing mistake: The protagonist starts his adventure in the triple-X rated world by gathering documentation. In the opening montage it's implied that he's making many trips to the store to rent different adult movies (the clock on the wall shows a different time and he dumps the cassettes on the counter each time in a different way), but every time it is always the same cassettes; different order but always the same ones - for instance a sky colored one called "Tricks", a bright pink one called "Untouchable", etc. (00:12:00)
