Also an honourable mention must go to the set builders who managed to make everything feel fittingly grim and period perfect.
Who made everything look like we imagine it looked like then is what you actually mean. Did anyone else not notice the new tenant ripping away wall paper made to look like it had been up for half a century to reveal a body showing virtually no signs of decomposition. Even when the builders came in they managed to leave everything looking as if it were older than when they started! Talented set builders indeed but totally misdirected by a design team who I guess were just wanting to give us what we expected.
Still made for very good telly though. Tim Roth was good but I think he took everything from Richard Attenborough’s portrayal of Christie in the 1971 film which is no bad thing as he was superb in that, as good and as terrifying in a very different way as he was in Brighton Rock.
