Some interesting stuff:
The Dam Busters

Oops!: There are a small number of minor errors in the film:
A series of shots of the Lancasters doing low flying practice finishes with three heading off into the sun ... but with the bombs already beneath the aircraft!
In the scene where Wallis meets Gibson for the first time, but cannot tell him what the target is, there is a very large framed print of the Möhne Dam on the wall!
