‘Operation Crossbow’ has always been one of my favourite films to watch; not exactly historically accurate and with plenty of movie nonsense in it but I just love the series of vignettes that make up the film. The ending with George Peppard in the power-house couldn’t be more dramatic and I loved Jeremy Kemp as the ‘German’ professor yelling at the German police!

The ‘special effects’ of houses being blown-up were simply created by ‘blowing-up’ (special effects) real houses and demolishing them (for real)!

I’m certain the V2 and trailer were genuine wartime examples.

The Hanna Reitsch V1 scenes were shot on Holkham Beach in Norfolk, a beach I know really well.
