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 M and his entourage arrive at Bond's estate, their cars are surrounded by sheep. They then drive on down an unsurfaced road to Bond's house, past a pride of lions he keeps on the grounds. A series of sweeping overhead shots shows us that it is all one huge field, with no fences or the like. Those sheep aren't going to last very long.

Factual error: At the end of the movie, they show a bunch of ducks flying. Those are not ducks, they are geese.
Suggested correction: This was intentional. This is a mostly Minnesotan team and the team is going home. While geese are technically speaking not ducks, they are the state bird of Minnesota and fly in a very similar manner to ducks. This was meant to be a symbolism of them going home to their state.
