Cornea (film and television studies, U. of East Anglia) situates selected films from the 1950s to the 1990s in order to place the thematic and formal concerns raised by science fiction films within wider cultural and historical contexts. She draws on reviews and previous scholarship, and also on pertinent academic theory to scrutinize the principles and aesthetic conventions of the films within the contexts from which they emerged.
