Contrary to popular belief Ridley Scott wanted a voice over, but he didn’t like how it was executed – he referred to it as ‘Irving the Explainer’. RS didn’t want the storyline to be dependent on the narration – he wanted the voice over to reflect the cynical tones in the Humphrey Bogart movies, which was a time honoured device for film noir.
It was thought in the end that the narration made it more accessible to a general audience.
Philip K Dick didn’t want it.
It was RS’s idea to include the live unicorn in the DC. The bit when Deckard picks up the foil sculpture, with Gaffs words in the background ‘It’s too bad she won’t live. But then again, who does? Deckard nods, acknowledging that he realises Gaff let her live – yet when the live dream Unicorn is included in the DC it takes on a different complexion – the nod that he’s a Replicant – superb.
Simply the best film ever made.
That’s the beauty of the film for me – in the end it’s not really about who is or isn’t a replicant, it’s a meditation on what it means to be human.
– and that’s probably the best summation you will get of the film.
