HOLLYWOOD — On St. Patty’s Day in Hollywood, we’ll kick things off by lathering up with a fresh bar of Irish Spring, cracking open a box of Lucky Charms, dusting off our old Sinead O’Connor CDs and taking in a screening of Green Zone.

OK, so that Matt Damon movie turns out to be set in Baghdad and not Blarney, but at least director Paul Greengrass was also responsible for Bloody Sunday, which was about the violent 1972 civil rights uprising.

Meanwhile, over in scenic Malibu, that Conan O’Brien fella, who can trace his lineage to County Kerry, Ireland, has been busily preparing for his upcoming comedy concert tour.

Since being strong-armed (or would that be strong-chinned?) off his Tonight Show perch by Mr. Leno, Conan has been tweeting up a storm, apprising his 600,000-plus followers of his next move.

Thanks to his loyal Twitter network, his 30-city Legally Prohibited from Being Funny on Television tour (Vancouver and Toronto are among the stops) is already a virtual sellout, even though it’s still several weeks away.

To get in stand-up shape, O’Brien has been dropping by the famed Laugh Factory on Sunset Blvd. (home to Michael Richards’ infamous racist diatribe) and trying some fresh material on for size.

Although his appearances have so far been unannounced, the other day we spotted the club’s electronic marquee proclaiming “Laugh Factory offers Conan O’Brien 11:30 show every night.”

It makes for a clever marketing ploy, but wouldn’t it be swell if Coco were to take them up on their offer, thereby competing with NBC without violating terms of his $45-million golden handshake?

NORTH DAKOTA: Last month we spread the word about an open casting call for the role of a young male actor, aged 10-14, to play the part of Hugh Jackman’s street-smart son in the DreamWorks boxing robot movie, Real Steel.

Well, they’ve finally found their Max (the pre-teen “with a hard, untrusting outer shell which hides a warm, enthusiastic spirit beneath”) with the highly-coveted part going to Toronto’s own Dakota Goyo.

The 10-year-old actor, whose previous roles have included playing Josh Hartnett’s son in the filmed-in-Alberta drama Resurrecting the Champ — he can currently be seen in the Woody Harrelson movie, Defendor — is expected to start work on Real Steel later this year on location in Detroit.

A Nov. 18, 2011 opening date has already been set by Disney, which will be releasing the movie as part of its new distribution pact with DreamWorks.

While we don’t know for certain if Goyo actually got wind of the career-making audition from this column, we prefer to think he did until we hear otherwise.

Go! Go! Goyo!!
