What things would you bring back from the 1980s? For the Americans, it appears to be old crime series. Yes, late last year Magnum P.I. was revived, and now Sky are debuting it in Britain. Jay Hernandez takes over from Tom Selleck in the title role – a private investigator and security consultant to the never-seen novelist Robin Masters. There are some big changes. Hernandez has no moustache for starters, and the role of Masters’ majordomo Higgins is now being played by a British actress (Perdita Weeks as “Juliet” rather than “Jonathan”). Magnum P.I. is on Sky1 at 21.00.
