Flipping thru the channels here on a Sunday afternoon I come across
The Hunt For Red October and reminded how much I love this movie. I'd guess this title will probably run away with the poll, but what the hell.
In doing the little bit of research for this thread, I was surprised to see there's only been 4 Jack Ryan films, I would've guessed there was at least one more Harrison Ford one.
I would expect
Sum Of All Fears will show up last in this, but I don't think it's a bad film at all, just that the others are that good. However if you haven't heard, Paramount is looking at rebooting the series yet again (Affleck's turn didn't last long) setting it sometime in the very near future (book not yet decided) and so far the new Capt Kirk, Chris Pine is being looked at for taking over the Ryan character.
