OK, the wife was out with the girls seeing a girly movie so I was home on my own, so I put on the 1968 film Battle of Britain. Some wonderful stuff there but of course there are many many things not right.
Some of them can be seen here:
Goofs but it fails to say much about the vehicle errors such as that old one, the US half tracks playing German vehicles. There are a few Dodge Beeps with the Germans in 1939 Calais and a lot more.
This is not to take anything away from some of the most spectacular flying scenes ever shot of course, even if almost every aircraft, both British and German is powered by a Rolls Royce Merlin.
What are some of the errors you have seen in Feature films?
