Science fiction
Science fiction (SF) as a genre is spread wide across different media, and different discourses (e.g. advertising, reporting of science) within them. This case study, updated in 2006, explores the 'repertoire of elements' which make up the genre, and in particular looks at Frankenstein fictions, and the Alien films for their relation to horror, and their treatment of gender expectations.
It also explores the 'what if' potential of SF narratives as that relates to our ability to imagine different futures, as well as SF's capacity to showcase cutting edge special FX. You might like to think how Avatar (US 2009) works in this context, as both an imagining of a 'greener' future, set against a militaristic 'war on terror' present, and as a showcase for 3-D, increasingly important for film and TV.
