OBLIVION

Last year’s surprisingly good Tom Cruise sci-fi vehicle introduced these spherical predators. Their malevolent features included red camera eyes, à la The Terminator, laser scanners straight out of a 90s rave, and four big guns, for shooting things with. Despite all this and the ability to manoeuvre like a very fast, airborne salmon, they were (spoilers!) nonetheless unable to chase Cruise through a canyon without crashing. Phew.
