A woman who calls herself Natalia on Twitter sent a tweet to her hero. "Hola Mark, love the last scene in The Force Awakens, very intense, can you say something in Spanish? Un saludo."
The 64-year-old actor, who has once again taken the role of Jedi knight in the latest of the Star Wars films after appearing in the original trilogy, did just that.
"Algo" - the word 'something' translated into Spanish - was his sardonic reply, a response that was retweeted more than 13,000 times within 24 hours.
The film "Star Wars: Episode VII - The Force Awakens" has broken box-office records since opening in Spain.
