A Bridge to the Sun
Just watched this film for the umpteenth time and it still makes me sad!
Based on the true story of Gwen Harold, a woman from Tennessee, who meets and falls in love with Hidenari Terasaki - secretary to the Japanese Ambassador, whom she meets at a reception in Washington DC. They marry in spite of opposition from all sides and go to live in Tokyo. There Gwen finds it very difficult to adapt to Japanese culture - especially the attitude towards women. In November 1941 they return to Washington with their young daughter and - in December 1941 the attack on Pearl Harbour happens. This, as you can imagine, throws their lives into chaos. She is despised for being married to a Japanese - he is despised and called traitor for having an American wife. They are hounded and endangered in both Washington and Tokyo.
I have no doubt that the story/film has had the 'Hollywood' treatment because it is different from the book in many particulars - but I still find it very moving. Their daughter - Mariko - went on to become a diplomat.
