What looks like a b-grade buddy film (there were plenty around this time and usually looking to be humorous), is far from it. Director John Flynn's 'Best Seller', which was written by Larry Cohen (who makes a crackerjack combination), is actually a stark, stinging and darkly witty and violent crime caper with an out-the-shadow concept. Novel writing (mainly the sharp exchanges and character inserts) and its zesty tempo couldn't be faulted. Even with its talky core, Flynn keeps it gustily hard-boiled and rancorous with its occasional action sequences and lean suspense. Knowing that it heavily relies on the performances to be successful, Flynn sets-up the film around the pairing of James Woods and Brian Denneby. Woods effortlessly vivid and unbalanced performance frighteningly commands attention and Denneby is sensationally rock-steady. The two worked off each other impeccably and build a sympathetic, but also conflicting edge that never feels forced. Cohen's biting script illustrates and develops quite a stimulating, random and unusual relationship between the two. While his usual social commentary (quite a familiar one) and plot devices playing second fiddle to the complex arrangement. The rest of the support cast don't quite have the same impression, but Paul Shenar and Victoria Tennant are good in their roles. The weak points would have to be that of Jay Ferguson's ugly sounding synthesiser score and a mishandled conclusion. A solidly rewarding crime thriller drilled home by two tremendous lead performances.
