Factual error: When we see the Spanish newspaper reporting the death of Kane, the title says "el Sr. Kane se Murio". No self-respecting newspaper would omit the accent on "muriĆ³". Also, Kane was supposedly a worldwide household word, so he would never deserve "el Sr.". Finally, the colloquial "se" is out of place in a printed title such as this. The title should simply be "MuriĆ³ Kane".
Factual error: When they are driving to the Everglades for a picnic, the sea is at their left. As Xanadu and the Everglades are on the Gulf coast, the sea should be at their right.
Suggested correction: That depends on which direction are you filming, north-south or vice versa.
