"Speed" wasn't the best movie in the world... but it was a fun watch... but it would have been very different if the top casting choices had actually made the movie... Forget Sandra Bullock and Keanu Reeves... how about Stephen Baldwin and Ellen DeGeneres...

And it's not just "Speed" there is a long list of stars that were almost in some pretty big movies... Like Molly Ringwald replacing Julia Roberts in "Pretty Woman"... or Tom Cruise as Tony Stark in "Iron Man"...
