In Firefox, Clint Eastwood, in a bold change of pace, plays a renegade computer programmer who invents a new web browser that quickly becomes popular, making him rich.

Sound dull? Unfathomably, the real Firefox, in which Eastwood (also directing) plays a burned-out pilot tasked with stealing “the most sophisticated warplane on the face of this earth,” is rarely more interesting. Well, at least it gives us another entertainingly eccentric performance from Freddie Jones (The Elephant Man) on which to chew.

There’s more than a whiff of the lackluster from the start, when Eastwood suffers what appears to be flashbacks to a stock-footage festival he attended while fighting in Vietnam. This debilitating dread, played up as a great demon he must constantly battle, manifests itself mainly through Eastwood sweating and dramatically pausing when he shouldn’t as he goes undercover in Russia. Fully two-thirds of a movie ostensibly about one kick-ass piece of weaponry is bequeathed to a lethargic spy thriller rife with bad accents, dull dialogue and rather unpleasant jingoism.

All this could be forgiven, perhaps, if the main attraction were at all interesting, but even here, despite some really neat effects work by John Dykstra (Star Wars), the plane is ultimately a letdown. For a film built around the concept of “the greatest warplane ever built … a Mach Five aircraft with thought-controlled weapons systems,” the filmmakers do precious little to make it seem unique.

It looks cool, sure, but after a wearing hour and a half of setup, finally arriving at the “Let’s see what this baby can do!” point, I expect a tad more from an action thriller than a half-hour of cruising altitude and refueling while Soviet generals argue with each other over where the plane might be. And when there is finally some bloody action in a long-promised dogfight the likes of which we presumably have never seen … we’ve seen it before, and better, and longer.

In film, there’s Eastwood classic (Unforgiven) and Eastwood junk (Pink Cadillac). Firefox, all buildup and no payoff, is Eastwood meh. —Corey Redekop

Tim Kincaid’s Riot on 42nd St. is so bad that it’s an argument for New York City officials’ Disneyfication of the area depicted — one of sex shops and flame steaks, of grindhouse theaters whose oft-flashed marquees were playing everything from Steele Justice and Penitentiary III to Masters of the Universe and Wet Hookers. Real wet hookers strut the streets outside to the tune of the Casio-clap soundtrack.

Having served time behind bars for killing a drug pusher, Glenn Barnes (John Patrick Hayden, Hot Tamale) brings his porn ‘stache and Haggar slacks back to the Deuce and more specifically, back to The Garage, the spacious theater owned by his family. Barnes aims to help them reopen it as a nightclub, thereby acquiring the wrath of Farrell (Michael Speero, She’s Back), the owner of the rival club across the street, Love Connection, where skanky women dance undulate in the altogether.

Farrell’s competitive business strategy is twofold: First, get his ladies to prostitute themselves to customers, and two, crash The Garage’s debut gala with automatic weapons. The latter proves more effective as his goons shoot up everyone in the place, whether they’re being entertained by high-stakes gambling, hoochie lingerie dancing, stand-up comedy (courtesy of actual “comedian” Zerocks, playing himself) or a woman crooning something about a “Uranus Child.” The shootout — with each group shown killed twice, the second time in gut-busting slow-motion — results in the titular riot. Then a cop played by future Lawnmower Man Jeff Fahey (in just his third movie ever) says something meant to be profound. Go home, people.

As cheap as dirt and probably as tasty, Riot on 42nd St. is punishing viewing that finds inspiration in repetition. Writer/director Kincaid (Breeders) flourishes with such incompetence, it all makes sense when you learn of his prolificness in the world of gay porn. This comparatively mainstream release is woefully flaccid, good only as a time capsule of the Big Apple’s sleazier, greasier times. —Rod Lott
