Firth spoke to journalists after the film’s first screening, joined by the film’s lead Gary Oldman – who plays George Smiley – and actors John Hurt, Benedict Cumberbatch and Mark Strong.
[Tinker, Tailor, Soldier, Spy] is a film which demands concentration and is far from fast-paced – the polar opposite of a Bond or a Bourne spy movie.
But Firth said: “I do think there is a tendency to underestimate audiences, I do think there is an appetite to be stretched. I do think people want to hear language at its best on the screen. I’m optimistic about it having an enormous audience.”
One reason a film had previously not been made of the novel was the brilliance of the 1979 TV series with Alec Guinness.
