Through the years the science fiction genre has amassed a following the likes of which few others could ever hope of matching. A bold statement, no doubt, but not an unfounded one because the truth is that everybody loves a bit of sci-fi.
With the genre's penchant for exploring both the unknown and the impossible, we've seen an abundance of films within it push the boundaries of cinema, using mind-boggling special effects and well-crafted narratives to make us think outside the box and essentially question everything we know. It's also gifted us with some of the greatest films of all time, so it's hardly surprising that it has more than a few admirers.
Yes, science fiction fans are everywhere, but it's probably safe to say that not all them are as well-versed as others. With that in mind, we've compiled a list of Sci-Fi movies that everyone who claims to be a film fan really should have seen.
If you've been lucky enough to experience all of these classics, then you should pat yourself on the back for absorbing all of this boundary-pushing knowledge. If you haven't, well then you'd better prepare to have you horizons well and truly broadened - literally and figuratively - because you're in for a very strange treat.
The level of success that Avatar achieved in 2009 rightfully earned it a place in conversations about the most groundbreaking films of all time, and we really shouldn't expect anything less from an unrelenting genius like James Cameron.
Written, directed, produced and even co-edited by the man himself, the larger-than-life spectacle centering on a war between greedy humans and a species of tall blue humanoids known as Na'vi really was just that. With stunning special effects and breathtaking visuals, it was acclaimed for being perhaps the most immersive cinematic experience of all-time. And the audience demand clearly reflected that as it went onto topple Cameron's own Titanic as the highest-grossing film of all time - a record it held for a decade.
Time may not have been as kind to Avatar as it has been to others on this list, with public perception of the film changing over the years due its bloated length and standard storyline, but the feats that Cameron accomplished on the big screen with this epic took science fiction filmmaking to new heights at a time when we thought it had peaked long ago - and that should never be overlooked.
