One obvious inspiration is Martin Scorsese’s GoodFellas (like that 1990 classic, Niccol’s movie depends on long passages of narration by the protagonist), but Niccol can’t match the headlong pace or resist a preachy, hectoring air (Scorsese never berated his audience for tolerating gangsters).
Niccol has clearly been inspired by films such as Goodfellas and Boogie Nights, and initially infuses Lord of War with a similar sensibility - complete with period-appropriate rock songs on the soundtrack (ie Eric Clapton's "Cocaine" plays during a drug-heavy sequence).
Writer-director Andrew Niccol, however, has already decided how he feels about it, and he isn't the kind of filmmaker to give you a down-and-dirty rise-and-fall story, like Martin Scorsese's GoodFellas or Ted Demme's Blow.
Typically, this type of device is a sign the screenplay needs revision, but it tends to work here in much the same way Ray Liotta's voice-over helps unify "Goodfellas."
But it's not the jolly Goodfellas' marina and Dino tinged streets of mobster lore.
Writer/director Andrew Niccol ("S1m0ne") takes on a huge issue and gives it the "Goodfellas" treatment, making his morally suspect lead a wisecracking narrator and entertaining guide into the glamorously evil world of gunrunning.
