just watching eagle has landed movie ..... as the american jeeps are going past a farm approaching the church to take on the germans , in the back ground is a yellow reliant robin with a blue roof !!!! oops !!!!!!!!
lol, maybe the Germans has the idea years ago, and Reliant copied the plans. They were into their 3 wheel vehicles like the Messerschmitt, but that was in the 50's.
Certainly a bug in the film, well spotted.
