The Hawaii Five-0 crew transformed an Oahu landmark into a busy set. Parts of the pilot were shot at the Mighty Mo and now episode six returns to Pearl Harbor for a hostage standoff.
"I think we all know that the pilot's definitely really good, the first episode is really good and if we can sustain that" said Scott Caan, who plays Detective Danny 'Danno' Williams.
In between scenes, the stars did dozens of satellite interviews to promote the new series in places like Dallas, New York, and of course, here in Hawaii.
"This has been completely unprecedented in my experience. The amount of publicity and marketing the show has been getting, not just here in Hawaii but globally. I got a phone call from a friend in London today saying that she has just been hearing all about Hawaii Five-0" said Daniel Dae Kim, who portrays Chin Ho Kelly.
The nationwide debut comes one week after thousands of local fans watched the first episode in Waikiki.
"I wasn't nervous until this morning and then I thought to myself, we're really going to find out after all the hoopla and all the hype, we're gonna find out what we got."
Fans are also curious to see if there will be some romance in the action-packed show.
"We find love, but it's platonic...kind of special love. Man love, 'bro-mance' style. I always find love, everywhere I go I find some love" said Alex O'Loughlin, who plays Steve McGarrett.
When they're not on the set -- the stars are exploring their new home. Scott Caan can't wait to start surfing again -- once he recovers from a knee injury.
"I like Kaisers a lot, Bowls, Ala Moana, I really like that place" said Caan.
"I'm learning how to surf. I'm trying to get to a point where I can actually stand up and look like I know what I'm doing by the time he can surf again" said O'Loughlin.
