FYI...I am just a a longtime Magnum fan, and a few months ago I heard 'Rick' (Larry Manetti) interviewed by Dennis Miller. Manetti mentioned he had a book out years ago about the whole Magnum thing. I ended up buying the book from Manetti because on eBay copies were $100+ (!).

I went to Manetti's website mentioned during Dennis' show:

(...inside I found that Tom Clancy had written a treatment for a post-TV Magnum movie...)

....'Chuck' is wonderful!
.....I also enjoy 'Burn Notice'...it has a bit of a Magnum P.I. feel, with the voice-over narration by the protagonist...
