Ahhh! One of my favourite ‘challenge Anneka’ 11th hour jobs. One where you get a call last minute from the production company is USA asking you to source mega specific costumes and props. I found the retro army helmet (after trying everywhere) in good old Camden market. Its ‘had’ to be dark green, couldn’t have a visor and preferably, had a white stripe down the front. The tweed suit and Barbour shirt were no trouble - now I think I know every tweed suit, in every costume hire place in London.
