If you think of British film companies of the 60s, particularly makers of genre movies, then of course you think of Hammer, then probably Amicus, and perhaps Tigon in third place. It might be quite a long time before you remembered Planet, a much smaller outfit these days best remembered for a couple of Terence Fisher films – Island of Terror, from 1966, and Night of the Big Heat, from 1967. Island of Terror was a moderately successful monster movie, rather let down by ropey monster props and a slightly stuffy tone. Night of the Big Heat (also known by the rather more promising title Island of the Burning Damned) almost looks like an attempt at a remake with these things fixed.
Everything takes place on the island of Fara, which we are told is somewhere off the coast of the UK. The film actually has a very unpromising opening, with no dialogue for ages and no real sense of what’s going on: someone’s radar set explodes in his face, a young woman (Jane Merrow) drives around in her convertible, and a stern-looking man (Christopher Lee) is engaged upon some mysterious experiments involving cameras and mirrors and bits of wood. (One of these scenes turns out not to have happened yet, and is just a teaser for much later on.)
Eventually we get some sense of the set-up here. Key locations on Fara include the weather station and the gravel pits (a useful location for staging mysterious deaths and the climax), but most of the action takes place in the pub, which is run by slab-faced alpha-male novelist Jeff Callum (Patrick Allen) and his wife Frankie (Sarah Lawson). Lodging in the pub is mysterious outsider Dr Hanson (Lee), while constantly propping up the bar is genial GP Dr Stone (‘guest star’ Peter Cushing). New on the scene is Jeff’s latest secretary, Angela (Merrow), who is a bit of a naughty minx: she and Jeff have history together, if you know what I mean, and she’s come to Fara intent on resuming their liaison. A torrid time is in prospect.
Especially torrid given the island is sweltering in the grip of a tremendous, unseasonal heatwave, which is making TV sets and bottles of beer spontaneously explode. (All the men have had ridiculous sweat-patches applied to their shirts by the costume department.) What’s going on? Does it have anything to do with Dr Hanson’s experiments?
Well, sort of. It seems that space probes from Earth have attracted the attention of alien creatures composed of ‘high frequency heat’ and they are using Fara as a beachhead for their invasion of Earth. Anyone who crosses their path – sheep, supporting characters, those old tramps who are such a regular feature of this kind of movie – is rapidly incinerated. Is everyone doomed?
The least you can say for Night of the Big Heat – you know, I do think Island of the Burning Damned is a better title – is that it more or less avoids the key problems that Island of Terror had: the alien monsters are kept off-screen for most of the movie (and the monster props are marginally better when they do appear), and the general tone of the thing is pepped up by some mildly saucy business between Allen and Merrow (not to mention Merrow providing some cheap PG-rated cheesecake thrills). And yet this is still a worse movie than the previous Planet production.
How can this be? Well, firstly, all the stuff about Jeff being unable to keep his hands off Angela, and her scheme to have her way with him, scarcely informs the main plot of the film – it’s filler, basically, and very melodramatic filler too. The characterisation of Angela is, shall we say, problematic: she is a one-dimensional Bad Girl, who functions primarily as a sex object, and she’s the first one to lose it completely as the situation grows increasingly dire. (On the other hand, at least she can type.)
However, at least this makes a vague sort of sense, which is more than you can really say for the alien monster invasion storyline, which starts off as slightly dubious and rapidly becomes very silly indeed; this is the kind of film you can imagine inspiring the Monty Python ‘Sci Fi movie’ sketch. As ever, you are left filled with admiration for Christopher Lee’s ability to treat this kind of material with a gravity and intensity it doesn’t remotely deserve. By the end of the film Lee is participating in expository scenes explaining how the alien invasion has happened which are basically utter gibberish, before running outside to implement his character’s ridiculous plan to see off the invaders (this involves many shots of Lee setting fire to haystacks with a flare pistol), and he genuinely seems to be taking it completely seriously. What a legend. Peter Cushing is, of course, equally good, though not in the film enough – though we do get a marvellous example of Cushing’s wonderful ‘death-spasm’ acting (let’s see Disney’s CGI Cushing do that).
Most of the film is fairly competently made, but the script is so thick-headed that it’s more or less impossible to take seriously as a piece of drama, and it’s not even particularly enjoyable as camp entertainment. Night of the Big Heat came out in 1967, coincidentally the same year as In the Heat of the Night. One of these films is a timeless classic that deservedly won critical acclaim and several Oscars. The other one is a dim-witted B-movie with Jane Merrow in a bikini and aliens defeated by their poor grasp of meteorology. You can kind of see why Planet Film Productions never achieved a higher profile.
