i saw this movie once in or close to it release year 36 year ago ( 1969 ) . although i can now only remember bit of it and i long to see it again . the part i remember and rightly or wrongly and include mustard gas in the trench and suzie kendall a a german spy and offer some bloke sexual favour in the back of an enclosed truck to get military information from him . the music score be especially memorable and emotion stirring in the league of go with the wind and i would love to hear it again . there must be some commercial or copyright reason why this movie be not available . anyone know why . i doubt it anything to do with a lack of quality or interest .
