An absurd script is navigated with brio and professionalism in the “Back in Action” comedy.

Jamie Foxx and Cameron Diaz summon up their old school cool and comical chemistry (“Annie”), Glenn Close trots out an accent and the quips and ass-kickings pile up like Audis in a CGI-assisted pileup at the end of any given chase.

Director and co-writer Seth Gordon is known for big budget, action-packed larks (“The Lost City”), and for not always making them come off (“Pixels)”). He lives up and down to both reputations in a movie with pizazz and pop that’s never so amusingly over-the-top that you forget what nonsense this all is.

But as you would hope and expect, Foxx is past his health emergency — hale and hearty and sometimes a hoot — swapping zingers with Ms. “Still Got It” Diaz as two spy-parents on the lam with offspring who don’t now how badass their elders are.

The American spies are sleeping together when we meet them, teaming up for an Alpine heist of this high-tech, world-dominating “key.” As the mission goes wrong and they survive a digitally unsurvivable plane crash, Emily lets out “I’m pregnant.” After viewing a “royal flush” of pregnancy test-sticks, Matt says, “My favorite person is about to create my new favorite person…I’m in.”

And they’re out — off the spy-grid about out of action as they raise two kids, Alice and Leo (McKenna Roberts and Rylan Jackson), in McMansion suburbia. A cliched viral video of them delivering ass-whippings in a club underage Alice has fake-ID’d her way into blows their cover.

But that key? They still have it, 15 years later. And bad guys aplenty want it. Still.

Forget the car and boat chases through Britain, on the A roads and on the Thames, the well-choreographed (and stunt-doubled) brawls and think about that. This 15 year old high-tech key…still works? Still is cutting edge tech? Still holds the possibility for upending the global power structure?

That’s like Chechen and Polish bad guys risking their necks to fetch an MP3 player.

None of this is at all serious, these “Mr. and Mrs. Smith” suburbanites, “Boomers” with a “Karen” included, coping with sassy, tech-savvy rebel kids, renewing old contacts (Kyle Chandler is their old control agent, Andrew Scott is Mr. MI-6) and visiting Emily’s rich, estranged “MI-6 girl boss legend” mother, played by Close.

Casting Foxx always means there’s a better joke on the set than in the script. That minivan Mom and Dad just trashed through armed villains in SUVs in order to fetch the 14 year-old and 12 year-old from school? “What happened to our car?”

“Long story short, don’t valet.”

Each star gets plenty of moments to show off their still-sharp skills in fight choreography, and their way with a one-liner.

“I need to feel like that bitch again!”

Michael Jackson jabs, “Can you beat up” so-and-so’s dad jokes, “full English breakfast” put-downs and a “Push It Real Good” sing-along are among the low-hanging-fruit gags turned up here.

Every fight is staged to vintage pop songs — from Rat Pack baubles and Nat King Cole ballads to Lauryn Hill and James Brown classics.

All in a tale where the kids are the last to figure out Mom and Dad aren’t who they seem. Are they crooks on the lam?

“They’re not CRIMINALS! They’re in a PICKLEBALL league! They watch HGTV!”

God help me, I laughed a few times. And God bless Foxx for luring Cameron Diaz back on screen, and for his recovery. They’re damned cute together, even if their movie isn’t all that in concept, writing and any scene that involves “inaction.”
