The latest addition to Hawaii Five-0′s arsenal of men with a commanding presence is Tom Sizemore, whom we will be seeing in Season 2 as the head of Internal Affairs!
Sizemore’s character hails from Detroit, where he was a homicide detective, and McGarrett will likely butt heads with him often while he and his team come under close scrutiny as IA delves into last season’s complicated chain of events.
We know Tom from Saving Private Ryan and Black Hawk Down and can look forward to his appearance in multiple episodes of Five-0 in the new season!
EW was the first to report the news, followed by TV Guide and TV|Line.

Thanks Mizz. I just found out that Tom Sizemore has been cast as the chief of Hawaii State Police’s Internal Affairs. He will be an asset on Hawaii Five-0.
