Shawn Wayans doesn't pull any punches, or punch lines, when it comes to describing his movies.

The writer-actor doesn't expect the audience to take them seriously. "Take your brain out of your head, sit down and just have a ball."

And, truth be told, some members of a "Little Man" preview audience were laughing so hard that they obliterated lines of dialogue. Others, whose brains just wouldn't shake out that night, were not laughing so much. Or at all.

"Little Man," directed by Keenen Ivory Wayans, is one long -- and admittedly, well done -- sight gag.

The comedy takes the head of 6-feet-2 Marlon Wayans and digitally attaches it to the body of a 9-year-old actor named Linden Porco. That allows Wayans to play a 2-foot-6-inch man pretending to be a toddler so he can retrieve a stolen diamond.

Wayans did his acting in front of a green screen, or blank backdrop, mostly alone. He has only his face at his disposal, and he can grin, grimace and groan or flash disgust, lust, playfulness or innocence at the drop of a diaper.

Of course, he does it in a movie about an ex-convict turned jewel thief that often goes for low-brow humor about genital size, breast-feeding and striking men in the groin with flying objects.

Wayans plays Calvin Sims who, minutes after being sprung from the state prison, rejoins his partner Percy P (Tracy Morgan) in spiriting a famous diamond out of a jewelry store for a crime boss (Chazz Palminteri). Thanks to some suitcase subterfuge, Cal reels in the rock but has to plop it into the purse of a stranger named Vanessa Edwards (Kerry Washington) when the police show up.

As luck would have it, Vanessa and her husband, Darryl (Shawn Wayans), have been talking about having a child, and Percy hits upon the idea of disguising Cal as an abandoned baby and leaving him on the couple's suburban Chicago doorstep. And they're off, with Cal trapped in baby rompers, fuzzy slippers and precious bonnets, and in a house with Vanessa's father (John Witherspoon), who is suspicious of the new arrival.

Somewhere, amid the football fracas, the hockey fights, the car chase and the costumed dinosaur, is a soft spot for dads and for a grown man who never had a family, let alone a birthday party. But you have to sit through a lot of people getting bonked with a frying pan or whiffle bat to get to it.
