Factual error: In the "Berlin intro" with all the German images, a plate can be seen with the text "automatische afsluiting" (automatic closure), which is not German but Dutch. (00:43:45)
Factual error: Near the end of the movie, when Mieka is shown in the Vatican, she is wearing a dress without any sleeves that does not cover all of her legs. This would never be allowed in the Vatican because of the dress code, which is long pants and long sleeves, and the same holds true for men's attire, such as shorts. (01:11:20)
Factual error: Near the beginning of the film there is a map of Europe with the countries coloured in using their respective flags. Great Britain is coloured with the Union Jack (Union Flag) pattern but so is the Republic of Ireland (Eire). The Republic of Ireland is not part of the United Kingdom (the political state) or Great Britain (the geographical term for the island), only the British Isles - they are a separate country and the Union jack is not their country's flag. Only the north or the Irish landmass (Northern Ireland) and Britain should show the Union Jack. If they are using an "old map" it would have to be very old, before the 1920's.
Factual error: When the group is seen traveling down the road next to the "walls" of St. Peter's square, the Roman Colosseum can be seen behind them. This is impossible because the Colosseum is far outside of the Vatican City Walls.
Factual error: When Scotty and Cooper are walking into the airport to get courier jobs to go to Europe, a European road sign can be seen behind them. It is blue with a red X on it.
Factual error: In "Amsterdam", before the characters go out, a famous Czech bridge is visible in the background.
Factual error: Amsterdam doesn't resemble the "real" Amsterdam at all, including the infamous Red Light District. When walking alongside the highway, it's clear that it's not a Dutch highway. The supposedly Dutch characters speak with an Eastern European accent, because the "Dutch" scenes were shot in Prague, the Czech Republic.
Factual error: In addition to the error revealed before: The group approaches the Vatican Museums from the left, which is impossible because of the Vatican City Wall standing there.
Factual error: After the climax at the Vatican, before the main characters are seen sitting and having a drink, there is a brief shot from inside the "Galleria Vittorio Emanuel II", which is in Milan, not Rome.
Factual error: When the guys drive from Bratislava to Berlin it shows them driving past the Black Forest on the make-shift map. In reality the Black Forest is located in the south-western most corner of Germany near the borders to France and Switzerland, so driving in a more or less straight line from Bratislava to Berlin would make them miss the Black Forest by about 550 km (342 mi).
Factual error: When the guys fly from the USA to London, UK, they fly with the German airline Lufthansa. The same airline takes them from Rome, Italy, back to the USA. Lufthansa is only allowed to directly connect US cities to German cities, not including third countries.
Factual error: In the very beginning of the trip, a map of Europe is shown. It shows Bosnia and Herzegovina as a separate country, yet it shows Croatia and Yugoslavia as one country. Bosnia and Herzegovina split from Yugoslavia after Croatia, so if Croatia and Yugoslavia are a single country, then Bosnia and Herzegovina should not be separate either.
Factual error: When Scott and Cooper throw the burning hat in the fireplace, the smoke is seen coming out of the chimney in the Sistine chapel. Though this adds a bit of hilarity, the chimney is only able to be used when constructed in preparation for the Conclave of all conclaves, the election of the new pope.
