Awww, how sweet. Our little Jim Carrey may finally be growing up.

All right, his latest film, “Fun with Dick & Jane,” isn’t exactly “Capote.”

It’s light, it’s energetic, and yes – fun, packed with plenty of opportunities for Carrey to mug, show off and strut his comedic stuff.

But he doesn’t. At least, not in every single frame of celluloid, like he did in the “Ace Ventura” movies or “How the Grinch Stole Christmas.”

Carrey teams up with Tea Leoni for this remake of the 1977 George Segal-Jane Fonda comedy about a couple who seems to be living out the American dream until the economic rug gets pulled out from under them.

He gets tapped for a coveted promotion at his high-tech communications company, not knowing his bosses are setting him up to be their scapegoat when the company tanks just hours later. As the corporation goes down in flames, Carrey loses not only his job, but his pension and savings as well.

After a few months, finances are tight and no new job is in sight.

Invigorated by a twisted sense of justice and the adrenaline rush of getting away with a crime, Carrey and Leoni turn to robbing convenience stores, coffee shops and banks.

The pair plays off each other well. Her strength and good looks complement his slightly frayed bravado. The sequence chronicling their robberies is fun, and provides Carrey with a great (if short) ad lib scene.

But I walked out of this movie feeling that something was fundamentally wrong with it. The couple has a 6-year-old son who’s essentially being raised by their Hispanic housekeeper. He speaks more Spanish than English – which is a setup for one quick gag later on. He’s never in a scene unless it’s to deliver the punch line. Like the kid’s parents, the writers seem to care about him only when it serves their interests.

And it’s unnerving to see the pair claim there are no jobs available after one failed attempt at lower-paying work. Their brief foray into the world of service workers isn’t even funny.

“Fun with Dick & Jane” works because Carrey manages to channel his manic energy, bumping up the physical comedy but keeping his character low-key and believable. Even with the screenplay working against him, he and Leoni are fun to watch.
