Revealing mistake: Most of the time, though not all the time, Leonard has no lenses in his glasses.
Revealing mistake: If you look at the marble patterns on the walls, they are all exactly the same from floor to floor. Also the bricks oddities on the stairway match from floor to floor. They change lights, elevator tape etc. but it's the same floor used over and over as different floors.
Revealing mistake: Any time that Leonard is "driving" his hands never move and the wheel never moves either.
Suggested correction: Not obvious at any point in the show.
