Film production used to employ a "Continuity specialist" to pick up glaring errors like these, but in the cost conscious world we live in I suspect this is no longer the case.
Most people neither notice or care, but it really irritates me.
A few years back I was sailing the Wherry "Albion" and we had a film crew on board making a program about how the Wherries carried goods etc to all the little villages around the Broads. Part of the cargo was big bundles of reeds which got everywhere. Now, being a bit of a safety freak whilst on boats, during a tea break, I swept the side decks clear of debris so as to limit the chance of anyone sliping falling in the drink. Those of you who are aware of continuity ( which I wasn't ) will feel for the poor chap whose job it was to put all the individual reeds back on the deck just where they were prior to the tea break.
