I'm hoping they cast an unknown for the part of Norton, someone really plain and ordinary looking as oppossed to a big name. Please, please leave the novel the way it is, just this once. I don't mind the twists on the original material, but I'd prefer it if they just stuck to the way the tale was told for this one.
Oh God, how are we all going to react to Poirot's death scene? Hugh Fraser is coming back for it, isn't he? (No reason why he shouldn't, but just fan paranoia)
