Naomi Watts and Ewan McGregor star in The Impossible, a film based on the true story of one family who were caught in the deadly Boxing Day tsunami eight years ago.

On December 26 2004 a powerful earthquake off the Indonesian coast triggered a tsunami that devastated countries around the Indian Ocean, killing more than 230,000 people.

The film - directed by Juan Antonio Bayona - is based on a story from one of the survivors, Maria Belon, a Spanish tourist who was lounging by a pool in Thailand along with her husband and three young sons when the tsunami hit.
