Some movies are better than others about building a meaningful sense of mystery, tension, or suspense. This is one of the others, which in a way seems weird coming from a production company that in a few short years would become known as a powerhouse of genre fare. 'The unholy four,' also known as 'A stranger came home,' is almost wholly bereft of such feelings. Above all, the acting is bizarrely even-keeled at all times, no matter what's happening in a moment, and this alone does much to firstly squelch whatever the title may have to impart, and secondly, to encourage an unanticipated nap from the viewer.
There are some recognizable names involved here, not least Michael Carreras, Hammer mastermind, who wrote the screenplay and produced this picture. Director Terence Fisher helmed no few films for Hammer, in addition to this one. Are Carreras and/or Fisher responsible for the dull tone that pervades this feature? That seems more likely than the notion that each individual actor sought to adopt the same blasé comportment for these eighty minutes, though I suppose I can't rule that out. Murder is committed, punches are thrown, voices are raised, and secrets are revealed, and all this and more plays out like the cinematic equivalent of the muffled speech of adults in any Charlie Brown special.
'The unholy four' is well made from a technical standpoint, and the crew behind the scenes put in good work. All the elements are here for what could be a compelling mystery, or thriller, or film noir, or some such something or other. As a finished film, however, this is just boring and grey, becoming tedious as the minutes tick by. Movies are supposed to make audiences feel something, or think, or become earnestly invested in some fashion; the most I can say for this one is that a single happy neuron fired off in reaction to a small moment, not directly involved in the plot, that comes shortly after the one-hour mark. The writing isn't terribly convincing in any regard, the direction is bland, and the cast just coast along, to the point that when they do try to strike a particular chord, it invariably comes across as overacting. Wait, why was it that I sat to watch this?
I don't know how this feature went so wrong. It just feels so very empty, however, and all the back and forth in the plot of "maybe this! Maybe that! Who knows!" seems like listless flailing more than sincere storytelling. Check out 'The unholy four' if you want, I don't care, but don't expect much, and maybe you'll somehow end up getting more out of it than I did.
