Above is a recent episode of Mr Vista which illustrates the point of being able to go 'off script' sometimes. The original story featured Mr Vista trying to hold back the tide on a sunny day. It was clear as soon as we arrived that a rewrite was needed. Plus the weather was so bad we couldn't literally stay out in it for more than about 15 minutes.
Luckily we are all fans of films like Mr Hulot's Holiday (Les vacances de Monsieur Hulot) by Jacques Tati. So we could pick something up and go with it - using it as a shortcut. For me, it goes to illustrate yet again the importance of understanding the themes and characters of a piece completely. PLUS always having the right people there. Get those right and anything can be overcome.
Extra points to actor Jonathan Rhodes for just going for it and doing silly stuff while we tried to hide in our coats.
