This oddball heist flick from directors Brian Koppelman and David Levien finds mobster manqué Matty Demaret (Barry Pepper) tiring of his pococurante existence as small-time errand boy for his pop, Brooklyn don Benny "Chains" Demaret (Dennis Hopper). So to prove he's worthy of dad's wise-guy love, he takes on a big-time errand: stewarding a cash-laden satchel cross-country for his old man. But after the dim pal (Seth Green) he's foolishly enlisted loses the filthy lucre in the middle of Montana, Matt and some fellow crime-syndicate scions (the ubiquitous Vin Diesel among them) head West to wrest it from a slimy small-town sheriff before dad's goons (led by a menacing John Malkovich) exact revenge.

A few solid performances -- notably Pepper's, a slow burn of corrupted conviction, and Diesel's as a Jewish tough -- compensate for the perfunctory pastiche of mob/teen-flick archetypes. And the sight of Hopper and Malkovich destroying each other in a ferocious handball set more than makes up for how ridiculous the young leads look in their matching dyed-black coifs.
