In the freshman action-drama’s 15th episode, Moore will guest-star as the deputy director of a tsunami tracking office based out of Honolulu. As some whopper waves threaten to deluge the islands — and with his boss mysteriously gone missing — Moore’s character proves very important to McGarrett & Co. during a crisis.
In addition to his roles as Avatar’s Norm Spellman and Bones squintern Colin Fisher, Moore has enjoyed a multi-episode run on Medium and very recently played a criminal hacker on Chuck.
Hawaii Five-0 airs Mondays at 10/9c on CBS.
