Who is the best science-fiction character in cinema history? It's a question that's been asked many times, yet movie buffs are yet to agree on an answer. That's understandable, when you consider how old and expansive the sci-fi genre has become.

Sci-fi began way back in 1902, with the release of French film-maker George Mielies' A Trip to the Moon. At first, the genre consisted mainly of low-budget B movies. But after the success of Star Wars in the late 1970s, we saw a boom in big-budget sci-fi blockbusters, starring heroes who quickly turned into household names: Luke Skywalker, E.T., Batman, Chewbacca, Spider-Man, Princess Leia, ... the list goes on.
