For most of its running time Enzo G. Castellari's The Heroin Busters is an exercise in lazy plotting and almost arbitrary box ticking as it flatly trudges through the usual cops and drug runners clichés, which wouldn't matter so much if the action scenes were better. Unfortunately despite a decent botched evidence room robbery, it's a film that's saving most of its ammunition for its grand finale. But when it comes, it's a grand enough finale for you to forgive a lot of the padding it took to get there, the final twenty minutes offering a prolonged chase through a subway construction site and the ruins around the Caracarla Opera that displays the kind of verve and imagination so much of the film had been lacking until then, and clearly influencing both Diva and Lethal Weapon 3 along the way. It's well worth waiting for.
David Hemmings' Interpol cop doesn't have much to do apart from make the odd bad tempered speech or copping a feel from an obliging girl on a motorcycle while Fabio Testi is his usual monolithic self as the new boy on the crime scene trying to work his way into the mob. If anything Joshua Sinclair's villain makes more of an impression if only by virtue of his untrustworthy pencil `tache, cigarette holder and English accent that makes you wonder if Terry Thomas is a role model to Italian drug lords. Surprisingly Goblin's score works against much of the picture, especially the opening sequence that clumsily moves between Hong Kong, Amsterdam and New York, and Massimo De Rita and Galliano Juso's script is often shoddily constructed in the first half but it does at least offer a couple of odd surrealist touches and a gratuitous lesbian scene to keep the audience's interest while you're waiting for the action to kick off. It's just a pity the wait wasn't a bit more interesting.
Blue Underground's NTSC DVD offers a decent widescreen transfer of the English language version with a rather unfocussed audio commentary by Enzo G. Castellari and the theatrical trailer as extras.
