Welcome to Hard Talk from the BBC World Service with me, Sarah Montague.

My guest, in an interview recorded on January the 6th,

is one of the most acclaimed documentary makers working today.

An Oscar and BAFTA winner, his films about Ayrton Sena and Amy Winehouse broke box office records.

But Asif Kepardia's latest movie takes him in a very different direction.

It melds news footage with

science fiction to paint an extremely bleak picture of what the world could be like in

2073, a planet destroyed by right-wing autocrats, tech oligarchs, climate change and our

And what you've done with this movie is to cut real footage of events now, whether it's protests, riots, effects of climate change,

with a fictional vision of the future, which, 2073,

which, I mean, it's a post-apocalyptic,

it is a terrifying world that you present.

I just wonder if the way in which you intercut these things, whether it is

fair, because you've also described it as a documentary. Is it fair? Fair is an interesting

word question to ask. What it is is based on fact. It's based on research. It's based on

interviews with experts. I wanted to make a film. I have made fiction films. I've made
