Slither is, in effect, an excellent, live-action, feature-length counterpart to a great old Warner Bros cartoon. That is to say, a combination of physical and visual madness overlaid with satirical, throwaway sophistication which ends up its caper plot while nourishing it to the full.W.D. Richter’s first produced script is a smash achievement in structure and dialog. James Caan is superb as a likeable paroled car thief whose incidental friendship with Richard B. Shull, an embezzler, leads him into contact with a bizarre set of characters, some in search of a concealed fortune, others determined to thwart the treasure hunt. The characters road-run over the countryside, where a couple of ominous black vans and several ordinary-looking businessmen create a mood of latent terror.
