Just when you think Andie MacDowell is ready for bland moms and grandmoms as her career’s third act, along comes Big Cat, her “Queen of Odom County” meth mama in “Red Right Hand.”

“We’re gonna stuff and MOUNT these mutha-(you-know-whats)! Make a SHOW it!”

It’s not a natural fit for her, but it is a most savage turn by Ms. “Four Weddings and a Funeral,” a chance to let her inner Appalachian Mountaineer out.

“Red Right Hand” is a blood-bathed B-movie, an Orlando Bloom star vehicle about a corrupt corner of Kentucky where Big Cat reigns and getting out from under her thumb is deadly business.

Somehow, Cash managed to do it. He’s a former enforcer for Big Cat with no means of support in the “Hillbilly Heroin/Hillbilly Welfare” belt, living in a cabin on his brother-in-law’s farm.

Big Cat or her best-selling product may have had some hand in the death of Cash’s sister. Now her widowed husband (Scott Haze) is farming and hiding in the bottle as Cash helps out, taking his school-oriented ninth grade niece Savanna (Chapel Oaks) to church on Sundays.

Garret Dillahunt plays the redeemed sinner pastor, a guy who you just know is more of an Old Testament “type” when the chips are down.

Big Cat’s minions have their hands all over Cash’s family, thanks to brother-in-law Finney’s “loan” with her. As is the way of such movies, piling goons into a vintage Chevy Nova to go rough the client up long before the note is due is just part of business.

Maybe Big Cat wants Cash back. Maybe his old pal, the cop Duke (Mo McRae) could help them out in a quid pro quo sort of way. Maybe the sheriff (Brian Geraghty) would be OK with that.

One thing’s for sure. An awful lot of people go missing as the body count rises, an awful lot of locals ignore the din of assault rifle shootouts, and that recent medical report that suggested guns were a big contributor to Red State deafness is backed up as Finney and Cash give Savanna some target practice, sans ear protection.

The script has the odd chewy line or pithy, Dead End America observation about small farms in Appalachia — “Like a bucket with a hole in it.” There’s an inevitability about where the plot takes us, which co-directors Eshon and Ian Nelms over-emphasize by making this 85 minute thriller stroll by at a leisurely 111 minutes.

Blunt instruments need to be wielded with speed.

But the shootouts are well-shot and reasonably well-conceived and edited. Bloom, sporting an ex-con’s abs and tats, is credible as the lead. And Ms. MacDowell does her damnedest to take this good/bad ol’gal places she’s never been as an actress.

“Red Right Hand’s” not quick enough to be the gritty mixed-bag B-movie that was its destiny, but the players, the place and pistol-packing might be enough for those who go for that sort of thing.
