+1 on Snow Crash and Neuromancer.
I'd add the Blue Ant trilogy - Pattern Recognition, Spook Country, and Zero History.
Dorsai - Gordon R. Dickson
The Flinx and Pip Series - Alan Dean Foster
Tunnel in the Sky - Robert Heinlein
And I'm not sure, but have any of the Travis McGee novels been made into films? If not, they should be.
