Revealing mistake: When Rose and her boyfriend are making a toast in her apartment we hear a perfect chiming sound. We can see that they're both holding their glasses by the bowl instead of holding them from the stem. Holding a glass this way would never allow a chiming sound.
Revealing mistake: In the scene where Hitch first meets Albert, Albert spills his soda. The can shoots open and spills over the steps. If you look closely the label on the can is upside down. This would be fine if the coke was spilling out of it but it shoots out and when he picks it back up it is still upside down.

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)
