I was fortunate to be able to attend an advance screening of "War Horse", Steven Spielberg's big screen version of Michael Morpurgo's young adult novel which was also translated to the London stage. Now also on stage in New York, the movie version is due to open to general audiences around Christmas Day. Given my special interest in the Canadian cavalry, I was very excited about attending the screening. I am restrained from doing a review, but I will say I was most impressed. The scenes involving cavalry action and fighting in the trenches struck me as very authentic.
