They are using a converted Yak 52 made to look like a Spitfire for the close up shots of the actors...
I won't post the pics I have of the large scale model Heinkels and Messerschmidts that I have. The film looks like it will have some great live action filming. I feel that the CGI filming in Red Tails, Pearl Harbour and Fly Boys really let the movies down. Let's hope that Chris Nolan's magic touch makes Dunkirk a classic for years to come.
Here is one of the Spits carrying the fictional LC markings on the Yak (which were the markings of Feltwell Station Flight) - the individual aircraft marks will be added afterwards apparently:
The other movie that is looking promising is Brad Pitt's "Allied" that has a full-scale Lysander in it. Filming has just finished and it's directed by Robert Zemeckis of Forrest Gump/Castaway/Back to the Future. So this should also be a good watch this coming November.
Locations for both are hush hush...
