This film is worth seeing as a good account of the Dunkirk evacuation. John Mills gives a fine performance. I agree with a previous comment that more time could have been devoted to the actual evacuation. However the time devoted to the group of UK soldiers moving through France helps to show conditions for the French people. Someone asked about where the Lock was. The Lock on the Thames where the small boatyard scenes were filmed is Teddington Lock. the suspension footbridge is still there as is the weir. Toughs Boatyard which is referred to in the film was on the River Thames at Teddington opposite the lock, it is now I believe demolished and been replaced by riverside apartments. Other scenes were filmed by the River Thames at Twickenham, along the embankment by Twickenham's Eel Pie Island. This still looks pretty much the same if you go there now.(Except for all the parked cars!
