In 5 years, this is only the second review that I have done on IMDb. The reason for this review is that there were only 4 other user reviews and this movie deserves much more so here I am writing a review. I started off watching by myself and a few minutes into the movie my son joined me. My son is an action movie buff and will usually leave the room if it isn't action so I was surprised to find him still there at the end of 'Castles In the Sky'. Not only was he still there, he initiated a discussion about the movie with respect to his new-found know knowledge of just how important radar was in helping Britain win the second world war. This movie was also very inspiring since Robert Watts developed radar in the face of adversity and very much to his credit, he was able to overcome many obstacles while under immense pressure. I know that myself and my son left this movie with a 'can- do' attitude. The acting was superb and even though it was a dark time for England, there was some light-hearted scenes which were thoroughly enjoyed by both of us. I can absolutely state that this movie is a good movie that I would highly recommend to others.
