Ridley Scott’s Blade Runner is widely regarded as a "masterpiece of modern cinema" and is regularly ranked as one of the great films of all time. Set in a dystopian future where the line between human beings and ‘replicants’ is blurred, the film raises a host of philosophical questions about what it is to be human, the possibility of moral agency and freedom in ‘created’ life forms, and the capacity of cinema to make a genuine contribution to our engagement with these kinds of questions.
