We did. In Thetford Forest. Honest. Whilst the sun beat down and our crew, in shorts, wolfed-down their picnic lunches, crystalline flakes were flurrying from a clear blue sky, the branches of the dense conifers began to turn white, and thick streamers of snow slid eerily into drifts. For this feat of alchemy we must thank our friends at Snowboy, whose white landscapes have adorned many a feature-film, and the Elveden Estate, whose trees grace hundreds of homes and town squares come Christmas. And the reason JMS turned the forest white? Sorry, it’s a secret for a month or two. But it’s sure to be magical. Just like snow in June.
