Update: Peter Lenkov leaks some Hawaii Five-0 Season 2 spoilers at PitchCon.org.
Alan Baltes is a casting agent who gets first hand info on casting calls, so I’d say this report is probably legit. It’s not an announcement of the second season, but it’s a good sign. Thanks to @lankyguy for the tip.
From Alan Baltes’ blog:
The CBS crime drama “Hawaii 5-0” is currently in production on season 2 and casting for principal actors, day players, extras, and stand-ins is underway. The series regulars are mostly cast out of Los Angeles, and the rest of the casting is done in Hawaii. Shooting takes place in Oahu, Hawaii.
101st Street Productions and Kurtzman Orci Paper are the production companies behind the series which has received mostly positive reviews, although recent ratings have dropped far off from the first season drawing 19.34 million viewers for episode 15.
“Hawaii Five-0” won the “Favorite New TV Drama” at the 37th People’s Choice Awards on January 5, 2011. Series star Scott Caan was nominated for a Golden Globe Award for Best Supporting Actor in a Miniseries or Television Film for his role as Danny. Actor Mark Dacascos, who played the role of Wo Fat in four episodes of season one, has been a fan favorite and will hopefully return for a series regular in season 2.
