Now and Then We Time Travel - Visiting Pasts and Futures in Film and Television (Paperback)

More than 400 films and 150 television series have featured time travel - stories of rewriting history, lovers separated by centuries, journeys to the past or the (often dystopian) future. This book examines some of the roles time travel plays on screen in science fiction and fantasy. Plot synopses and credits are listed for TV series from England, Canada, the UK and Japan, as well as for films from around the world. Tropes and plot elements are highlighted. The author discusses philosophical questions about time travel, such as the logic of timelines, causality (what's to keep time-travelers from jumping back and correcting every mistake?) and morality (if you correct a mistake, are you still guilty of it?).
