MAGNUM PI star Tom Selleck has snubbed the chance to reprise his most famous role in a movie version of the hit series. A film adaptation of the show, which ran for eight years attracting huge audiences, has long been rumoured, with George Clooney once mooted to play the mustachioed private investigator. But Selleck insists he will play no part in any plans. The 61-year-old star says, "I won't be in it and I won't be doing some stupid cameo."
