18. 'Blade Runner'
The early 1980s were basically utopia for nerds. New and exciting video games were hitting arcades every month, home computers were suddenly available and Star Trek was back in a huge way – new movies were hitting theaters and they were actually pretty good. So just imagine the excitement in the nerd community when they learned that Alien director Ridley Scott was teaming up with Harrison "Han Solo" Ford to make a movie about robots in the future. Blade Runner exceeded their expectations in every way, and over 30 years later they're still arguing about whether or not Harrison Ford's character was a replicant himself. (The general consensus is that he was.) There's been much talk of a sequel in recent years, but Harrison Ford's involvement in the new Star Wars films may make that difficult.
