Ewan McGregor and Naomi Watts star in this ecological horror movie, based upon the true story of a family divided by the 2004 tsunami that destroyed parts of Thailand. Directed by Juan Antonio Bayona, The Impossible is a harrowing retelling of events through the eyes of a father and mother who are struggling to escape the unthinkable. Oftentimes disturbing and graphic, The Impossible is nevertheless uplifting in its message of survival. If you're terrified of drowning, best to avoid the extended ten-minute scene towards the start.
