Heh, I knew it wouldn't be long before the dog controversy started up.
Personally I agree with ORAC. If there's even the slightest chance that hand wringing revisionists decide that altering the past to suit today's morals is the way forward, the whole dog angle should be left out of the film. There's plenty of other things concentrate on and having a dog called "Off-white" or something would just p!ss everyone off, insult history and divert attention from the story of the crews. Sorry state of affairs, but there you go. It's going to occupy a lot of column inches whatever.
Good CGI above - however the biggest issue I have with CGI creations in aviation films is generally not their appearance but the physics of flight, which is generally shocking.
Still, Jackson, a self confessed Anglophile and military aviation nut is probably the best man to hold the reigns so fingers crossed. That Kiwi article above says they're building ten full-size Lanc mockups for the ground shots. That'd be quite the sight!
