Science-fiction and horror go together so well, don’t you think? There’s a rich heritage, from the misty past of The War of the Worlds, via Alien, up to the present day.
There is, I suspect, an intersection at the point of the unknown. We fear the unknown, and yet the great unknowns offered by SF fascinate us as much as they intimidate us. That fear, for me at least, is the one of the things that really interest me, and so I am drawn to films like The Last Days of Mars.
