Science fiction and socialism have always had a close relationship. Many sf novelists and filmmakers are leftists. Others examine explicit or implicit Marxist concerns.As a genre, sf is ideally suited to critiquing the present through its explorations of the social and political possibilities of the future. This is the first collection to combine analyses of sf literature and films within a broader overview of Marxist theory and critical perspectives on the genre. Covering a rich variety of examples from Weimar cinema to mainstream Hollywood films, and novelists from Jules Verne and H.G. Wells to Kim Stanley Robinson, Ken MacLeod and Charles Stross, this is an indespensible insight into how Marxism and science fiction go hand-in-hand.
