Not so much a film as a concatenated version of a Saturday morning serial. As such it rapidly moves from one cliffhanger to the next, with plenty of 'futuristic' rocket chases, jet packs and fiendish situations, Our square-jawed protagonists do battle with the distinctly unzombie-like Martians in a bid to thwart their plan to blast Earth into deep space and move Mars into its orbit. Mindless but thrilling fun.
