Coming to America 1988
Starring Eddie Murphy and Arsenio Hall.
Near the end of the movie the King of Zamunda played by James Earl Jones goes to the home of fast food restaurant owner Cleo McDowell looking for his son Prince Akeem(Eddie Murphy).
Outside it is pouring down with rain when the king, his wife and his retinue ring the doorbell and enter McDowell's house. We can see from an inside view from the house that it is apparently pouring rain outside. Yet the king and everyone with him enter and are completely bone dry.
You would think that for come consistancy some of the king's attendants would have been carrying umbrellas but nobody has one. So how could they have got from their limousine to the front door of McDowell's house without a drop of rain on them?
This is especially inconsistant as some effort was made to establish that it was raining outside as when the door opens we can see rainwater pouring off of the roof behind the king.
Of course se all know that it was shot in a film studio.
