Yep, it remains a nice movie. I have the DVD-box with a second DVD which contains 4 documentaries from which one with the story how they made the film. Its amazing, but with the current digital possibilities, most likely the last time they did it.
BTW The BBC made a very nice documentary which is called the true story of the Battle of Britain. When you ever have the chance to see it, you must! Highly recommended. It contains some very interesting and surprising facts.
Enjoy!
