MrShoestring and I went to see this film for free in exchange for an honest review ! It was much better than we thought it was going to be and ended up giving it 5 stars.
It was lovely to be able to go and see a film that both of us enjoyed, very often when we go out we make a bit of compromise but this was enjoyable, thoughtful and full of tiny details about life in the 1940s which we really enjoyed. MrShoestring's Dad was an actor who was just starting out in those times so we also enjoyed all the in jokes and recognising things that he had talked about doing.
That said there are also several scenes which brought home the reality of war and although it has a 12A classification I do not think that I would take anybody younger than 13 to watch it. There is also a bit of full on swearing and some extra-martital relations, so that is another reason not to take children.
We especially enjoyed all the 'inside' information about making films, for example drawing scenes on glass and then filming through it to add details to a landscape and I was fascinated by all the hand knits which everybody wore.
I think that we would have paid to go and watch this, it was that good, so if you do get the chance, go !
