Through out the miniseries you see cars driving on the right-hand side of the road. This story takes place in Australia where they have always driven on the left side of the road. Additionally, the cars in the film are left-hand drive instead of RHD.
The name of the farm is mispronounced. It is named after the Irish town Drogheda. The American cast did not know that 'gh' in Irish is pronounced like an 'h' in English. The cast said Drow-Geeda whereas the proper pronunciation is Dro-huh-duh, where Dro is pronounced like in "drop".
