What do Terry O'Quinn, Scott Caan and Tom Sizemore have in common? Not much! But they'll all be appearing on Hawaii Five-0 next season. Sizemore is the latest cast addition, joining the show as the head of Internal Affairs (!) for a multi-episode arc.

You'll recall Sizemore has had a boatload of personal problems in recent years, but that didn't stop CBS from scooping him up for this role. Here's guessing he goes rogue at some point? Just sayin', the dude has a history of going bad onscreen. (And off.)
