Watched this film recently. It is about the Boxing Day Tsumani in Thailand and the true story of a family who were there. Very good film. The 10 minute scene of the initial disaster took over a year to film, some of it quite shocking. Although not as bad it reminded me of the start of Saving Private Ryan. Good story though and very watchable, good cast - in particular the eldest son!
Stuck with me long afterwards and I looked up both the young actor and the actual story.
Well worth a watch.
