Who Stars In The Reboot: Hawaii Five-0 Cast & Character Guide

Hawaii Five-0 is an action-drama series following a compelling central cast of characters fighting crime that hits the shores of the titular state. The show follows a former Navy SEAL who moves back to Hawaii to avenge his father’s death and finds himself leading an elite special response team tasked with fighting criminals and gangs in the island paradise. The show proves an action-packed affair, filled with shootouts and high drama but grounded by the bonds between the characters, particularly the friendship between Hawaii Five-0 leads Steve and Danny.

The series is a reboot of the classic series Hawaii Five-O, which aired on CBS from 1968 to 1980, and it features many of the same characters, as well as the same beloved TV theme song. The series is one of three classic police shows recently rebooted by Peter M. Lenkov. The new Hawaii Five-0, MacGyver, and Magnum P.I. make up “The Lenkov-verse,” a shared universe of crime shows that often cross over with one another. Hawaii Five-0 is the first and most successful entry in this universe, running for 10 seasons while seeing a shifting cast of talented actors filling out the roles among the task force.
