When you search "Harold Perrineau" in What to Watch on roku.com, you get nothing. However, he was in several programs that are available on Roku, including The Unusuals, Lost, and an episode of Dead Like Me. I particularly liked him in The Unusuals, a cop show loaded with quirky characters that sadly was only a summer replacement for The Good Guys. He and Adam Goldberg play secondary roles, but are worth watching along with stars Amber Tamblyn and Jeremy Renner.
Roku needs to update its database of programs and actors.
