No Room at the Inn

I saw this film when I was very young and it had the most amazing effect on me. My Mother took me to the cinema I think not realising that it was to be so disturbing. I now work in the caring industry and have a highly developed sense of justice, fairness and the importance of treating people as you would wish to be treated yourself which I attribute largely to this film. I will never forget it - it is the most haunting film I have ever seen. I would really love to be able to see it again from my adult perspective but cannot find it. Can anyone tell me where I might get a copy? If I had to chose one scene which affected me most it would have to be when one of the children was locked in the outside coal shed - I am now a claustrophobic and can't bear to be shut in anywhere! What a legacy to have been left by a film!!
