Tom and Jerry Blast Off to Mars

This journey into the lives of the cat and mouse double-act sees the duo jettisoned into outer space after they stow away on a manned mission to Mars. On their journey they discover that humankind (along with mousekind and catkind) are not alone in the Universe after all, and end up thwarting a planned earth invasion by the Martians! If that wasn't enough eye-popping cartoon action, they also encounter an asteroid field, and a huge, vicious robot. (official distributor synopsis)
