Developed by Peter M. Lenkov, Alex Kurtzman and Roberto Orci as a reimagining of Leonard Freeman's classic series and shawrun by Lenkov for the show's entire run, Hawaii Five-0 has been a strong profit generator for CBS. In addition to its solid ratings performance, initially on Monday, and as a Friday anchor for the past seven seasons, Hawaii Five-0 has been a big international seller for CBS TV Studios, seen in more than 200 countries.
Hawaii Five-0 will end its run with its original stars Alex O'Loughlin as McGarrett and Scott Caan as Danno. I hear both of their current contracts are up at the end of this season. O'Loughlin suffered a serious back injury during the early seasons of the show, and has been dealing with effects from it ever since. There was speculation that he may leave the show two years ago but he stayed on after receiving stem cell treatment.
Hawaii Five-0 currently stars O'Loughlin, Caan, Ian Anthony Dale, Meaghan Rath, Beulah Koale, Katrina Law, Taylor Wily, Dennis Chun, Kimee Balmilero and Chi McBride.
Like most long-running series, it went through multiple cast transitions. That included the controversial exit of original co-stars Daniel Dae Kim and Grace Park after Season 7. Returning for the two-hour finale are recurring cast members James Marsters (Victor Hesse), William Sadler (John McGarrett) and Mark Dacascos (Wo Fat).
