Continuity mistake: In the scene where Shirley and her daughter Milandra argue about Shirley going on holiday, Milandra gets out of bed and dresses quickly, her shirt is tucked into her jeans. She walks out and the camera angle changes to a view of her front, her shirt is now loose outside her jeans.
Question: In the scene where she is walking home in the rain after visiting her prostitute friend, in the background you can see 3 huge "tank" like structures. They are made twice as high by open girder and cable contraptions. The same things can be seen in the movie, "Spider", starring Ralph Fiennes. What are they?
