In all other regards however, there is extremely little likelihood that audiences might have confused A.P.E. and the original King Kong – King Kong is one of the greatest of all monster movies; A.P.E. is laughable in every respect. The effects work here is shockingly bad. The scenes of the ape destroying a ridiculously unconvincing model ship and then wrestling with a rubber shark at the start of the film are a clear indication of what is to come. The scenes that follow with the ape rampaging through and smashing obvious plywood houses and, in a couple of hysterically unconvincing model shots, stepping over a toy cow and batting a hanglider and pilot on a visible wire, produce gales of laughter in their ineptitude. Scenes of destruction go on and on without even the slightest degree of directorial conviction of dramatic interest being created due to the fact that the film eschews almost any type of optical shots whatsoever – we never see any shots of the ape and people together in the same frame. Although the reason for this could be that the three optical shots we do see that patch the ape over stock background shots of Seoul are some of the worst travelling matte shots in the history of special effects. The ape suit is immobile in expression and one can clearly see the eyeholes that have been made in the mask for the actor inside. There is stock footage of military vehicles on manoeuvres repeated several times throughout, which are meant to stand in for the massed military attack against the ape.

A.P.E. was originally made in 3D but has only been seen flat in the West. Thus there are an inordinate number of shots with extras throwing burning spears at the camera, soldiers rushing into the camera to pose and shoot, and the ape throwing the same rock on a wire at the camera.

There is the odd occasionally amusing line – “Let’s see him dance for his organ grinder now,” says the general as the military shoot the ape down. The hero’s end epithet for the ape – “He was too big for a small world like ours” – raises unintentional laughter. Alex Nicol at least gives an amusingly hard-headed performance as the American colonel (and should get some award for having to yell an entire performance into a telephone). In every other regard however, A.P.E. is an appallingly bad film – the most amusing thing about it was its 1983 retitling as Attack of the Giant Horny Gorilla.

Director Paul Leder made a number of other exploitation films, including the wackily titled psycho film I Dismember Mama (1972); My Friends Need Killing (1976) about a venegful Vietnam Vet; the psycho film Sketches of a Strangler (1978); the Old Dark House film Vultures (1983); and the psycho films The Baby Doll Murders (1993) and Killing Obsession (1994). In an interesting trivia note, Paul Leder is the father of Deep Impact (1988) director Mimi Leder.
