Martin Clunes plays with relish the real life Acid Bath murderer, John George Haigh in made for television film.Haigh was a fraudster who came from a strict religious upbringing. He turned to murder supposedly on the premise that if they cannot find a body you cannot be charged for murder. Something he was wrong about.Presumably his motive was money because as an inventor and gamble he was not much cop. He did well with fast cars, women and being charming. He was also handy with an acid bath where he would dump the murdered corpses which in time would dissolve.The film looks very nice but its ultimately shallow like a lot of ITV drama films that rely on its star and the production design rather than depth in its screenplay.We know very little why he killed. Was it an addiction? Haigh also killed several strangers a crime he confessed to after his arrest.A decent enough drama but it amounts to being just average.

I saw this TV-made film for the first time last night. I know "sociopath" and "psychopath" are labels and that everyone is an individual and no label, even attached to a mass-murderer such as Haigh could really explain his actions which can only be described as destructive and evil. Martin Clunes was clearly relishing the role and I have to say, I found him completely convincing in it. Whilst the adaptation does suggest the strict religious sect his parents adhered to was a strong influence in his development into a psychopathic murderer, I think this film interpretation of his character indicated he had a sense of entitlement to taking what he wanted in life and he had no boundaries, no conscience, saw no reason why he could not do what he wanted to do to get it all. He would appear to be one of those people who believes their own lies to the extent they can successfully convince many others. I think the reason he committed the murders was because he could and he seems to have committed them for personal gain. He had none of the normal moral and ethical boundaries in place to prevent him. He was unable to understand or foresee the consequences of his actions. Since the explanation he was influenced by his religious background came from Haigh himself, who was a practised and pathological liar, I leave it to the experts to determine whether such people as Haigh are the products of nature or nurture or a tragic combination of many contributing influences.

I have just seen a repeat of this TV film and was very impressed. I had the opportunity of doing some gardening work for the Sgt Inspector Heslin (Ret'd) before he died, when he lived in Torbay. As one of the detectives who interviews Haigh and discovered his gun, he showed me photographs which very much resembled the film set of Haigh's workhouse. I also specialized someone in the RAF when, as a medic, I saw just what Sulphuric acid can do. Now I am a prolific author and wish I had taken more notes about this case. Heslin and I enjoyed good conversation and he was very proud to have been one of the main detectives to interview Haigh.Peter Carroll

My only problem with this movie is Martin Clunes. He acts it well, but is so often shown on TV as an extremely affable and likable character that it's almost impossible to believe him as a serial killer. Be it in fiction ("Men Behaving Badly") or documentary (about both dogs and horses) he always comes over as a jolly nice chap (which I'm sure he is). Casting him as a cold-blooded serial killer just doesn't work – it worked when Leone cast the blue-eyed angel Henry Fonda as a psychopath in "Once upon a Time in America", but casting Clunes as a serial killer is a step too far.Having said that this is nonetheless a gem of a movie. Set design is pure '40s and the use of 1940s music is extremely well done. Hence my 8/10 rating.
