I have long said that in order for any comedy to truly succeed as a story, there has to be meat beneath the jokes. There has to be that moment when it is not funny any more.
That sequence occurs in the grim no-man’s-land between English and German
battlefield trenches. Though Diana has been told she can’t cross it and must play by man’s
rules, she takes it upon herself to save women and children threatened
by the Germans. It’s a very powerful moment. We have a
character committing to her true self, doing what she believes needs to
be done.
