“Stupid is as stupid does,” and stupid’s entirely the point of “Get Fast,” a dumber-than-dumb action pic that sets out to prove how much movie you can make with pretty much no script at all.

Catch-phrases and stock characters, a film where every heist or attempt to recover the loot from a heist “always ends with a shootout,” it’s a short, stupid sprint of a low-budget action comedy, the sort of picture you get when you have to digitally add muzzle flashes to those “shoot outs” because you blew through way too much money renting a plane, a helicopter and a pricy “cowboy” outfit for the biggest name in your cast, Lou Diamond Phillips.

But take your ten gallon hats off to Valerie Biggin, who arranged the generic ’80s action pop soundtrack. That sets the cheesy tone they were going for here, and if they had fun doing car and truck chases, shoot-outs and the like on a teensy budget, well at least that’s something.

Director and co-writer James Clayton, who directed, co-wrote and co-starred in the Vinnie Jones thriller “Bullet Proof,” drops us right in the middle of the action, the climax to a chase where “partner” Vic (Philip Granger) isn’t able to fly his vintage plane to the rescue of “The Thief” (Clayton), who has robbed the drug gang run by Nushi (Fei Ren).

As Nushi’s minions Sly and Tank (Lee Majdoub and Simon Chin) and others show up to foil their getaway, partner Vic mutters “Get fast, get gone.” And the thief steals fresh wheels to make a getaway that never quite gets away.

There are dirty cops (Alisha-Marie Ahamed and James Hutson) and mob minions to overcome, an anxiety-ridden ice cream truck driver (Suleiman Abutu) to hijack and enlist and Nushi’s murderous “enforcer,” Mr. “If she’s sending who I THINK she’s sending” to be faced.

That would be “The Cowboy” (Phillips,) dolled up like New Mexican pimp ready to strut his stuff and wave his over-sized six-shooters at the Waco rodeo.

“Get Fast” is all action and arsenals, as our hero and villains have an unlimited supply of military grade ordnance which they unload on each other hurtling down backroads in black SUVs and a Chevyvan with Loverboy playing on the cassette deck.

The dialogue isn’t much, and at least one player’s slim grasp of English grammar — or the screenwriters’ — can make one cringe.

But this was never going to be much, and just the barest hint of effort at cooking up one-liners and pithy exchanges wouldn’t have been enough to save it. You can sometimes get away with a just-getting-by budget on your C-movie actioner by getting quick and getting witty. “Get Fast” doesn’t get over.
