Aaron Eckhart throws himself and some mid-fight grace notes at “The Bricklayer,” another CIA agent brought back in to “fix” a screw-up run amok within and without The Agency.

It’s not “The Beekeeper,” but Eckhart commits to the part and he and the fights in it are some compensation for a pretty silly plot and clumsy “Will this never end?” story structure.

It’s the latest B-movie by Renny Harlin, who once filmed a “Die Hard” sequel way back in the last millenium.

Eckhart plays a meticulous retired agent who brought his detail-oriented skills back to his pre-CIA profession — bricklaying. But somebody agent Steve Vail used to “run” when he was stationed in Greece has gone rogue. His former boss (Tim Blake Nelson) and the agent (Nina Dobrev) who discovered that the assassin Victor Radek isn’t dead are the ones who track Vail down.

“This is your f–k-up,” bossman barks. “And you need to fix it.”

Clifton Collins, Jr. plays the most conspicuous professional assassin in screen history as Radek — black outfits, black turtleneck, Homberg hat. He’s an aged hipster hitman, standing out in every crowd in sunny, touristy Greece.

These days, Radek is luring journalists with some sort of “doomsday file” that could expose decades of CIA misbehavior. He then kills them and makes it look like The Agency did it.

But back in the day, Vail and Radek were pals. Flashbacks show us a family, sailing vacations along the Greek coast, the promise of identity-changed “retirement” in Pine-something-or-other Montana.

Now, Radek wants blackmail money or he’ll keep killing journalists and creating anti-CIA/anti-American headlines all over Europe.

There’s nothing for it but for Vail to go back to Greece, dragging Agent Bannon (Dobrev) along as he reconnects with his “outfitter” (Oliver Trevena), his CIA station-chief ex-girlfriend (Ilfenesh Hadera) and invents a new “cover” as he tracks his old friend.

Bannon will pretend to be “my wife.” “You’re too old to be my girlfriend,” he explains.

He quotes Miles Davis whenever she catches him in contradictions.

“If you understood everything I said, you’d be me.”

And Balkan men?

“They never really die. They just smell that way.”

So yes, the dialogue has some snap to it. And Eckhart gives his all in a four or five big fights/shootouts, which Harlin (“The Long Kiss Goodnight,” “Cliffhang”) knows how to film and edit into a furious, pulse-pounding blur.

But the silliness isn’t limited to Collins’ satorial splendor. There’s a souped-up James Bondish Mercedes our agent gets to drive on chases (“Move over,” the sexist barks to Bannon when she’s in the driver’s seat).

And before all the intrigues, traps and double and possible triple crosses are done, our hero will have to explain “why a bricklayer” because the screenwriters ordain it. Corny scripts over-explain.

Suffice it to say, I found this “Bricklayer” about three bricks shy of a load.
