Other mistake: Throughout most of the sequence in Hugh Hefner's office, the framing of the camera cuts the main character's head off. This is not a cinema error, this is bad framing. The framing fixes itself then goes back to cutting the character's head off.
Other mistake: Meryl is renowned for her accents. But in this film, her accent comes and goes, for example, when she's sitting for her second exam for cordon bleu, her accent is gone completely.
Other mistake: When Lupin brings the princess back to the palace by car after meeting Conan at the cherry tree, he drives by a street sign that says "St. SANTIHUU34" and one that says "idajfojafas;" Even if Vespania is a fictional country, it does not seem to have a fictional language, and we can say with sufficient certainty that semicolons do not belong in city or street names. (01:15:05)
Other mistake: Inspector Clouseau concludes Miss Solandres was the thief by looking at her license plate and discovering he gave the car a fine 2 days before she claimed to have arrived in Paris, 1 day before the Pink Panther was stolen. However she told Clouseau her car was a rental moments earlier, therefore he should've assumed the fine applied to the previous renter as Clouseau had no reason to doubt Miss Solandres' story at that point. (01:10:00 - 01:25:00)
Other mistake: In the scene where Jenny waits in the car outside an apartment building while David helps a family move into their flat, an older woman looks out of the window of her flat. We see her reflection in the window of the car Jenny waits in. However, the car is standing beyond the corner of the building - there are no windows that could possibly reflect in the car's window.
Other mistake: Van Ryberg shoots two grenades from his rifle at the robot, and big fiery explosions are seen. No grenade from that rifle would have fuel type explosion like that.
Other mistake: The DVD cover that has older Dren posing naked with her tail blade or stinger exposed shows her hands on the far right side crossing, and her hand has five fingers. In the movie her hands only have four fingers.
