Apart from the German and Allied uniforms in this film, there's not much else to it. I mean, come on, they painted German markings on British spitfires and funnily enough the Brits looked like they were flying Curtis f...展开ighters (US-made). And the whole sequencing of the air battles looked so fake, as if from a 1930s film. And some of the air shots looked like they were done in a studio with arm-sized aircraft models!! Did anyone remember the tank battle as well at the end. The 'German' Panzers were actually American Patton tanks, built around the late 40s. It just looked so amateurish and cheap when you compare it to a film like a Bridge too Far, made ten years earlier (and which I concede had a much bigger budget). I mean, why bother with air and tank battles when you can't even make them look half realistic? The other thing i noticed was that all the explosions that were supposed to be stopping the 'Panzers' actually exploded beside or in front of the tanks, and yet the tank would come to a grinding halt!! Ridiculous.
But I'll admit the military action not involving tanks and aircraft looked decent enough (such as when Peppard infiltrates enemy installations to plant explosives, etc.) But overall the acting was wooden, mainly from the main actors. The only good performance was from George Hamilton who played 'Maurice', a French commando. Peppard himself was ok, but he did have a better acting scope than this which was not utilised.
