Whatever laughs are inherent in a caper comedy pairing up Peter Dinklage and Josh Brolin as twin lowlife thieving siblings caught up in “one last job” that involves their thieving mama (Glenn Close), Oscar winners Marisa Tomei and Brendan Fraser, with M. Emmet Walsh and an orangutan thrown in, aren’t so much coaxed out in “Brothers.” They’re flogged, beaten and dragged kicking and screaming from it.

Director Max Barbahow (“Palm Springs”) and screenwriter Macon Blair “(Small Crimes”) park these players and plot elements in a frenetic, slapsticky Southern (ish) farce of the “Logan Lucky” or “Masterminds” variety. As in very broad, Southern and “tries too hard.” Far too hard.

Most of the laughs in it catch you by surprise — that orangutan and its “role,” over-the-top sibling tussles, at least one of which causes a car wreck. But “over the top” is the default mode here, and the picture strains and groans from the burden of it.

The clumsy crooks can be funny. A backhoe chased by enraged golfers in carts is a laugh. Fraser as a corrupt, spitting-mad prison guard is a hoot. But what’s here doesn’t quite jell into a romp that romps.

Jady (Dinklage) and Moke (Brolin) are twins who grew up in the family stealing and armed-robbing game,” learnin’ by doin’,” Jady narrates. But Mom (Jen Landon plays her as a young strumpet) and her “cool” beau Glenn (Joshua Mikel) went wrong one time too many some 30 years before. And left on their own, Jady — how his sibling pronounced “J.T.” as a child — and Moke weren’t clever enough to keep Jady out of prison.

Years later, he gets out and tracks down his gone-straight sibling so that they can recover the Koenig emeralds Mom and the late-Glenn stole decades before.

If he doesn’t, hulking prison guard Farful (Fraser) and his equally corrupt judge-dad (Walsh, in his final film role) will have Jady’s hide.

Moke, his sibling’s belittling nickname for him, is now Mike, “gone straight” with a wife (Taylour Paige), a mortgage and a baby on the way. He has to be tricked and bullied into doing Jady this “favor,” which turns out to involve their still-on-the-lam mom (Close).

Jady starts piecing together what they’ll need to accomplish this mission by hooking up with an old flame (Tomei), which is how Moke meets her “spirit partner,” the orangutan, a “partner” with “urges.”

“Brothers” is the sort of yahoo farce that hunts for funny in character names — Crabcake, Gamma and Dad-Daddy among them.

Some of it works, too much of it doesn’t. The pacing is fast enough in stretches, the performances amusingly broad and the pratfuls and punches sometimes deliver a chuckle.

But at the end of the day, if “yahoo” is what you’re going for, you can’t skimp on the banjos. Ask Soderbergh (“Logan Lucky”) or Galifianakis (“Masterminds”). They’ll tell you.
