Behind the scenes

Amazing to think that the poignant, oft-celebrated and much-loved conclusion to Blackadder Goes Forth was a happy accident born of the fact that they had so little usable footage, isn't it? I'd be interested to know a bit more about what the cast disagreed with the writers on - if the actors did indeed "run away with it", as Tony Robinson has suggested, it's hard to imagine that whatever Richard Curtis and Ben Elton had scripted could have been any better.
