I'd also say any John Sanford and Clive Cussler for me - two of my favorites.
Barbara Hambly's "For Those Who Hunt the Night" - would be a great Vampire movie (speaking of which I drank a beer on SuperBowl Sunday named Nosferatu)
Robert Heinlein's "Stranger in a Strange Land" & "Starship Troopers"
Robert Silverberg's Majipoor Chronicles
I guess I read a lot of science fiction.
