Audio problem: After the part where Johnny Depp finds his bookstore friend dead, he gets back in the cab. After driving for a while, he tells the cab driver to pull over to the phone booth. The cab driver says something like "OK, yes sir" but you can see the cab driver's lips in the rear view mirror, and they never move.

Factual error: Throughout the film, the supposed rare book experts smoke over and around the books and always handle the books with their bare hands, instead of cotton gloves. Either one of these could destroy the extemely rare books.

Continuity: As Corso leaves Quinta Fargas, he barely dodges a speeding car aiming to ram him. Clasping his canvas bag tightly, never dropping it, he presses his back against a large tree. As the camera cuts to a close-up, the bag is suddenly a yard away from him, on the ground.

Factual error: In Sintra, when Depp and the girl go to Fargas' house in the morning, they ride the motorbike and turn left. However, from Hotel Central to this house you must turn right, it's the road that climbs to the manors, the other way you'll get to Central Village.

Other: Toward the end of the movie, as Johnny Depp and his leading lady are being led down into the dungeon, you can actually see the camera bouncing and shaking and hear it hitting the stairs as it moves down the stairs.

Audio problem: While Depp is at 'P y P Ceniza Restauracion De Libros', one of the bookstore owners (man on right side of frame wearing blue apron) says, "I would never have believed she'd parted with it, never." He obviously did not say this. He actually appears to either ask his brother a question or make an entirely different statement.

Continuity: At the very end of the movie when Depp is fighting his employer, Depp falls through the floor with his glasses falling to the tip of his his nose. But in the next shot when his employer looks at him, his glasses are all the way up by his eyes. His arms are tied by the floor meaning he couldn't have done it himself.

Visible crew/equipment: In the scene where the man in the suit and the woman wearing all black are fighting, if you look closely you can see the string used to pull the podium holding the book.

Factual error: Depp descends from the long-journey train (you can see it's the same train) from Toledo in Sintra. However, no long-journey trains stop in this station, just suburban trains: a direct travel Toledo-Sintra is impossible.

Visible crew/equipment: When Johnny Depp meets Boris for the first time there is a crewman reflected in the glass window of the library.

Audio problem: When Liana hits Johnny Depp over the head with the bottle, you can hear the sound of it breaking before it actually does.

Continuity: Throughout the movie they show Johnny Depp with non filter Lucky Strike cigarette packages. Throughout the film you can see clearly that he is smoking cigarettes with white filters then sometimes with brown filters and again sometimes without filters.

Continuity: Corso has reached Paris, checked into the hotel, and is sitting by a desk in his room to examine the charred remains of the Fargas copy. Look at the tumbler of scotch in this shot. It contains almost an inch of whisky, with ice cubes, and it's standing directly on the wooden desk. Now, as the angle changes and we see Corso from behind, the glass contains very little whisky, no ice cubes, and is standing on a white napkin. It's also more to the right of the book than it was. We can also see several scraps of paper, and what looks to be crumpled tissue, that wasn't there in the previous shot.

Continuity: When Johnny Depp is being shown into Baroness Kessler's room he pulls the strap of his book bag over his head to the other shoulder.  Then when he is seen next, it is no longer over his head.
