Asif Kapadia

My wife Victoria Harwood was art director on 'Far North,' and she had designed my student film, 'The Sheep Thief.'

I often make films about subjects I don't really know much about. Maybe it's laziness, but I don't go in there having done a tonne of research; the research happens while I'm making the film.

Why make a movie about Ayrton Senna? Someone who drove around in circles at 200mph in a car that looked like a giant cigarette packet? Why would anyone who isn't already a fan of Formula 1 care?

As the mother of a grown son with a traumatic brain injury, I couldn't be more excited about the prospect of finding out how to repair even a small part of the damage that changed his life.

I'm a big action junkie. I grew up on the '80s action movies - the bad ones and the good ones.

My background is in filmmaking, and my mentor is Dusan Makavejev, who combined fiction and documentary.
