Director's commentary:
Raphael did not understand his role, and he approached me on the set one afternoon. "What sort of things does a Dumbass do?" he asked, affecting an Etonian accent instead of his regular voice, also an affectation. "How might a Dumbass behave?" Good thing they don't hand out Oscars for not understanding your role, because Raphael would have to buy himself a bigger mantelpiece. Anyway, I don't allow acting in my films so I fired Raphael at the end of production ... and I think you'll agree that it made all the difference. Enjoy.
