I should read the book. This is truly a great film. I always did prefer Alec Baldwin as Jack Ryan to Harrison Ford. Harrison would have stolen the show against Sean Connery and, to some extent, James Earl Jones. Alec Baldwin fit in much better. I especially like the character development between Ryan and the captain of the Dallas from when Ryan first gets on there. That was very well written and for an action movie, was an astonishingly character-driven sequence!
Oh, and there's only one season of Firefly, sadly. But they made a movie: Serenity. It played in the cinemas down under, which was a bit odd considering the series never aired. I've got both; I have to finish watching the series before I watch the movie.
