The play's ambiguity has led to diverse interpretations in performance. Laurence Olivier's 1944 film, made during the Second World War, emphasises the patriotic side, ignoring the fact that the enemy of the play, the French, were in fact allies in that conflict, while Kenneth Branagh's 1989 film stresses the horrors of war. A 2003 Royal National Theatre production featured Henry as a modern war general, ridiculing the Iraq invasion.
