Replacing a teacher who was killed in a tragic accident John Ebony and his wife arrive at an English public school . Teaching 5B a class of truculent boys they insinuate that they killed the previous teacher . Ebony disbelieves them but when they state that they did in fact murder the previous teacher and threaten that he will be next Ebony starts to worry for the safety of him and his wife An early cinematic effort from John Mackenzie UNMAN WITTERING AND ZIGO is one of these films you vaguely remember watching years ago and despite having an instinctive memory of it as not being very good something about it sticks in your mind . This was the case with me and thought perhaps being 15 years old Carolyn Seymour's Silvia Ebony who sizzles repressed sexuality might have had everything to do with that but there's more to it than mere teenage hormones . What it is that the premise is very persuasive and what might have been an outrageous idea does become somewhat credibleThe problem is that it doesn't seem developed all that well . Watching it after a gap of decades I was constantly reminded of how stagey some parts of the film were and wasn't in the least surprised that coming to this page I found out it was originally a play by Giles Cooper . Mackenzie probably tries his best to make it a cinematic film but this isn't really the sort of premise that can be all that cinematic since it's a small type of thriller and the screenplay isn't all that special

"Unman, Wittering and Zigo" is a thoroughly peculiar and strangely uncanny gem from the early 70's Brit-movie industry; an era where lots of long-lost forgotten movie classics are still waiting to be re- discovered by cult fanatics. The film lacks explicit bloodshed or exciting actions stunts, but it thrives on ominous atmosphere, a solid and complex screenplay and impeccable acting performances. David Hemmings, perhaps the most shamefully underrated actor/director to come out of Great Britain, stars as a young and still ambitious teacher who enrolls in a strictly catholic male boarding school in the remote British countryside. He takes over class Lower 5-B since their previous teacher died in a most unfortunate accident when he fell off a cliff. When trying to bring some order and discipline amongst the rebellious young men and threatening to give them Saturday afternoon detention, one of his pupils suddenly states: "our previous teacher also wanted to that … and that's why we killed him, Sir". From that moment onwards, the students are provide more and accurate proof that they, in fact, did kill their previous teacher and scare Mr. Ebony into believing that the same might overcome him or his lovely wife Sylvia. Obviously no one believes him – not even his wife – and the pupils continue to push further their blackmail and menacing. "Unman, Wittering and Zigo" (the title refers to the last three names on the alphabetic list that Mr. Ebony runs through to see who's present in class) is a slow-brooding chiller with an immense claustrophobic power. By this I mean that director John MacKenzie manages to make it so obvious that nobody in John Ebony's immediate surrounding even suspects the pupils of anything, whereas he finds himself trapped in a isolated situation of fear from which he cannot escape. To everyone else, the pupils of class Lower 5-B are sophisticated and well-mannered young men and only their teacher knows that they're actually deeply disturbed and nihilistic psychopaths. There are a handful of truly powerful and perturbing sequences, including near the end with John's wife trapped in the school's gym, as well as a terrific use of the contemporary British life-styles and the remote setting. Unfortunately, the film also contains a few defaults, like a largely unsatisfying climax and some dead-end plot lines, but overall I would definitely say this is a gem well worth seeking out and treasuring.

When a school teacher dies in an accident, his replacement quickly begins to suspect his students of murder.Using its theatrical origins to claustrophobic effect, Unman, Wittering and Zigo very cleverly builds up layer upon layer of tension and menace, as Hemming's naive and idealistic Mr. Ebony is quickly and easily outclassed by his pupils, seemingly at every turn. Dismissed by his headmaster, and humoured by both his wife and a fellow teacher, Ebony is slowly ground into submission by the boys as they repeatedly claim to have killed his predecessor. However, when the boys attempt an assault on his wife as a way of further controlling Ebony, the web they have spun begins to unravel until eventually another tragedy forces out the truth.Chilly and chilling, Mackenzie is well-served by his actors, both adult and juvenile. Hemmings captures just the right note of bewilderment and impotence, whilst Seymour turns the potentially thankless role of Mrs. Ebony into a striking portrait of independence, determination and naturalism - her performance during the attempted assault by the boys is quite brilliant. Standout amongst the boys are Hoye, Owen and Cashman, all conveying stonewall confidence collectively, whilst allowing just the faint trace of fear and uncertainty when separated from their classmates. Unsettling allusions to Ebony's ambivalence and a vaguely sexual response to his ordeal add to the mix, and only a slightly dissatisfying and unbelievable conclusion mar what is otherwise a deeply disturbing, grown up story. Highly recommended, if you can track it down.

It's a very peculiar movie, which perhaps could only have been fully explained in semi-supernatural terms, although it never takes that step. The later sequences where murder seems entirely possible (particularly as they terrorize Seymour) are very unsettling. The movie is also a pretty effective exploding of the public school upper-crust ethos, depicting the boys as determined to get good university scholarships (perceived by them as the next thing to a divine right) while doing as little work as possible. That aside, it's not very ambitious or enormously distinctive - the portrayal of the school beyond the class itself is pretty vague and Hemmings' specific strategy - focusing on finding the ringleader - is fairly indistinctly plotted. Leonard Maltin's review refers to the actual killer's identity being revealed after closing credits but that wasn't the case in the print seen here (quite a let down, actually). The movie should surely have reached further into metaphor or broader meaning or SOMETHING. But even so, it kept me watching until 3.15 am one morning.
