Not to be confused with the Otto Preminger-Graham Greene-Tom Stoppard spy drama, 1975's The "Human" Factor is a bit of downmarket Death Wishery that - Charles Bronson being otherwise engaged - George Kennedy managed to fit in between Airports. No mere architect but an electronics expert at a NATO base in Italy, when terrorists kill his family he's able to track down the killers by using John Mills' unfortunately precipitously named 9/11 computer programme while Raf Vallone's portly cop tries hopelessly to stop him doing something he won't regret. There's an odd mix of British and Italian names in the credits - aside from Edward Dmytryk in the director's chair, Barry Sullivan is the most prominent American in the supporting cast while the presence of Canadian Shane Rimmer offers a sure sign that it's a British film (or in this case an Anglo-Italian co-production) pretending to be an American one, and a fairly cheap one at that. Despite a cheesily misleading poster where all the film's key characters are depicted running and firing handguns despite most of them being unarmed through the film, action is thin on the ground and not especially well executed (it doesn't help that Kennedy's stuntman on a rooftop chase is considerably more svelte than him), the photography poor and one of the most notable things about it is that Ennio Morricone recycled his chase music a couple of years later in Exorcist II. A weak film for Dmytryk to end his chequered career on, it does at least offer proof that it's never a good idea to hit George Kennedy with a shovel - it'll only break and then you'll be sorry.
The US DVD includes a decent interview with Kennedy, stills and poster gallery and TV spot, though the print quality - as with the original cinema release prints - is not particularly good.
