Goofs

When Harry and Marieke are on the run, she is wearing a green top. When they are in the culvert hiding from the police she's still wearing the green top, until they kiss. Then the top has changed to red, but they're still in handcuffs.

While Harry contemplates the blank canvas in his Dutch studio, the smudge on his cheek becomes thicker/darker.

Harry Donovan seems to have been testifying (and trying to paint a van Rijn) during the prosecution's case. After he failed to complete the painting ("Only a Rembrandt can paint a Rembrandt") the prosecution goes back to calling other witnesses.

There is an order of proof. In the English (and U.S.) trial system the prosecution goes first. The defense then goes and has to decide whether to call the defendant (accused) during its part of the case.

Harry Donovan and his father talk in the phone about the exchange rate between US Dollars and Dutch Guilders. Later on, when still in Amsterdam, Harry buys some sort of old painting in a shop. He pays however, in German Marks.

The sound effect used for the British police cars was inaccurate. British police cars did once sound like that but that was over 20 years ago. They now sound similar to American police vehicles.

When Harry Donovan is in Amsterdam and tries to buy painting in two different shops, both shop owners speak German and not Dutch.

There is no place all over Spain called 'Villa Perdita.' In fact, 'Perdita' has no meaning as a Spanish word. The correct spelling is 'perdida,' that means 'lost.'

At the very end, when they spin and kiss, Jason Patric clearly looks right at the camera.

The letter to Juan Del Campo was either done by a non-Spanish speaker or as joke. "La Granja Mierda" translates to: "The Shit Farm"

When Harry is opining on what might have caused the portrait to go missing 350 years ago, he includes saying it might have been taken by Napoleon's generals who were not on the scene until 150 years after the loss. Considering that Harry seems to be quite the expert on history, it's strange for him to make such an anachronism. Considering his propensity to make wisecracks, he was engaged with a business partner discussing their plans and he was being very serious.
