CBS said this week that James Caan, father of series regular Scott Caan, will appear on the show next month. The original Five-O series did the same thing, where that program’s Danno, James MacArthur, got to work with adoptive mother, Helen Hayes, in an eighth-season episode.
Meanwhile, for May, CBS is planning a two-night Five-0/NCIS: Los Angeles crossover, according to a Jan. 11 post on the TVline Web site.
And, at some point, CBS is bringing back Edward Asner to reprise a role he played in the original Five-O series for multiple episodes. That, of course, creates all sorts of continuity issues because new Five-0 is a “reboot” (i.e. starting all over again), rather than a continuation of the original. But nobody is worrying too much about that.
UPDATE: We missed this one. Dennis Miller is also going to appear in a February episode, according to a post on the Digital Spy Web site.
