World UFO Day is today (July 2nd) and as a librarian with a passion for classic horror films, I though it would be fun to celebrate the occasion with some of my favorite classic Science Fiction chillers. The titles on this list all have one thing in common: they feature some sort of creature from space. From man-eating vegetables to spacemen, and giant blobs to giant robots, we have a little bit of everything on this list!

Humanity is shocked when the alien Klaatu and his giant robot, Gort, arrive at the United States capital with some chilling news.
