It's true that Bladerunner is a iconic film. It's was adapted from a Phillip K Dick story but soon took on a life of it's own. ... (Ah Roland Barthes (1915 - 1980) again : Death of the Author)
I have known film students write their dissertation on this film. It works on so many levels, and when that happens it's a magical thing. What Blade Runner is - Is a magical film. You can count them.... Casablanca - It's a Wonderful Life - Manhattan - Angel Heart - Withnail & I .....
Or are they just my magical films?
I remember watching it at a late night showing in Derby at the Metro. I drove home to Nottingham with the roof back on my 2CV playing 'Memories of Green' on repeat.
Vangelis is such an integral part of the film. As music always is, but in this case I would argue that the music IS the films emotion. (mise en scene)
The narrative attempts to access emotion through character's - but holds back. Even the test to test for emotion in the replecant holds back. The fear felt is not full fear. In fact all the emotion feels fake or hidden.
