Alex O Loughlin

For someone so new to Hollywood, Alex O'Loughlin is very Hollywood. "Do you mind?" he said, motioning toward his pack of cigarettes while sitting poolside at the Roosevelt Hotel earlier this week. "Or are you going to write in the interview, ‘and then he lit a Camel?'" It's not that the 33-year-old is consumed with his own image — like some industry A-listers — but that he already understands its importance. Even the outfit he was wearing, which he would show off later that evening on " Jimmy Kimmel Live," had been selected by a stylist: distressed jeans, a pair of quirky bright green boots and trendy skinny tie. It was a look far different than the one he has in his new film, "The Back-Up Plan," out Friday, in which he plays a cheese farmer — yes, really.

During the tense and sweaty "give me my brother or I'll- kill your father" terrorist negotiations that open CBS' new " Hawaii Five-O," a viewer might find herself surprisingly distracted. Not by any allegiance to the original — though one of TV's longest-running shows, "Hawaii Five-O" has been reduced in cultural memory to its classic opening music and the catchphrase "Book 'em, Danno," both of which are present and accounted for — but by the show's lead. And not for the reason CBS would hope.
