Mexico City, May 6 (IANS/EFE): They've had everything in life and never had to lift a finger - until one day their dad decides to teach them a lesson and puts them to work. So goes the storyline of "Nosotros los Nobles", a comedy causing a ruckus in Mexico by raising awareness about the risks of spoiling kids.

"The movie has really shaken some parents. I get messages that they haven't been able to sleep after seeing it because it makes them wonder what kind of an upbringing they've been giving their children," director Gaz Alazraki told EFE in an interview.

The film has become the biggest box-office hit in the history of Mexican movies with $18.3 million (13.9 million euros) in tickets sold in one month, while becoming one of today's favourite topics of conversation.

Some moviegoers laugh because "they identify, they feel they know those characters", while for others "there is deep pleasure in seeing rich kids having to do things that other people have to do every day".

"Nosotros los Nobles" tells the story of three siblings in a high-society Mexican family, whose father has given them everything in life, until the day he realizes he must do something so they can begin to look after themselves. So he invents a bankruptcy.

Alazraki is happy not only because of the success of his first feature film, but also for contributing in some way to raising awareness and changing some small elements of everyday life.

About the comments and criticism, he said that what he likes most is that young people are saying "they love the movie", even though "their credit cards are going to be taken away".
