When I first saw this film about 5 yrs ago I was excited because I was unaware of the film and I read a preview in the TV listings that said some was filmed in Gravesend,my home town. The location filming was excellent but certain things grated on me like the tea shop in the middle of nowhere on the marshes down river from Gravesend where any passing trade could not have supported a business also the detective in regulation raincoat and hat who followed John Mills into the tea shop.I have now watched the film again today and enjoyed it much more and would say it is a little gem of the time and genre. I am still thrilled by the location scenes in Gravesend,not quite Carol Reed's Third Man but very atmospheric, the street near the river is much changed today but the small church like structure clearly seen in background shots was a seaman's mission and is still there today also in one shot you can see the spire of St Georges,Gravesend's parish church which is where Princess Pocohontas is buried.I feel John Mills really conveys the feeling of a man with a 12 year grudge and the scenes with Ilse where the grudge melts are beautifully portrayed.In his autobiography John Mills describes the film as "an extremely good thriller" but infers that director Bob Hamer had a drink problem and describes him as twice while filming night shots he fell into the Thames while walking backwards looking through a viewfinder!
