O'Loughlin Talks 'Hawaii Five-0' Season 4 Secrets

Hawaii Five-0 is entering its fourth season, and the tension and twists have never been more explosive.
In anticipation of the coming firestorm during the Season 4 premiere, ET's Brook Anderson sat down with Five-0 star Alex O'Loughlin, who plays Steve McGarrett, to talk about the upcoming season and what it has in store for fans.
When Season 3 ended, McGarrett was in a precarious situation, but as usual, he manages to find a way out. 
"McGarrett is in a lot of danger," said O'Loughlin. "He's always in a lot… he's in so much danger, this guy. I get anxious about it. I get home and when I go to bed I go 'God, I'm so worried about McGarrett.'"
"[But] he always seems to find his way out of a pickle, doesn't he?" O'Loughlin joked.
Check out the video for more special Season 4 secrets, including McGarrett's looming love triangle, Hawaii Five-0's move to Friday nights, and what it's like to work with TV icon Chi McBride.
Season 4 of Hawaii Five-0 premieres September 27 on CBS.
