OK, I’m going to display my chronic ignorance here – what outtakes are these and who are the ‘Dark Blue World crew’?
Battle of Britain is another film that might profit from some CGI magic, think of seeing the He111s and Bf109s with DB engines! We could do with modifying the long noses and double rads of the Spitfire IXs and XVIs too!
The ‘stuka’ scene is very obviously modelwork, perhaps we could even get some new air combat sequences now that so many Hurricanes are in airworthy condition – but that is probably far, far too much to hope for!
THE outtakes – there must be a cubic arseload of them in the MGM vaults, and I reckon we’ve probably only seen about 20% of them!!

*EDIT
Sorry, I’ll elaborate. The film crew shot many hundreds of hours of footage involving the aircraft, both in the air and on the ground. I think possibly only 40 MINUTES of that ended up in the finished version of the movie!!
