Magnum P.I.

9PM, SKY ONE

Jay Hernandez sports a goatee rather than a moustache in the Tom Selleck role of this new Magnum series, which makes a splashy start – in space, believe it or not – and rolls along in fun fashion. Higgins (Perdita Weeks, left) is female, British and ex-MI6, and fans of the similar Hawaii Five-0 reboot will spot a familiar character in episode one.
