The local cinema is showing Polanski’s The Ghost Writer and this is the poster advertising the film: 
You’ll notice that the title has been translated into Spanish as El Escritor – The Writer. I wonder whether that’s because the word used for a “ghost writer” is negro.
It’s an official term defined by the Real Academia Española as:
17. m. Persona que trabaja anónimamente para lucimiento y provecho de otro, especialmente en trabajos literarios.
It occurs to me that the translator might have been trying to be politically correct when he chose not to call the film The Black, but it would be quite unusual in Spain for political correctness to be an issue.

Then there’s the Cola Cao (powdered drinking chocolate) song that starts “Yo soy aquel negrito del África tropical que cultivando cantaba la canción de Cola Cao.”
In comparison, the Don Carbón logo from the barbecue coals we used at the weekend seems to be quite inoffensive.
