Amy Lou Wood is particularly heartbreaking"
Scott: "Yeah, because I totally agree with you because there's a scene, it's such a 'blink and you'll miss it' moment - there's a moment where Jodie Whittaker, her character, is having an argument out on a public street. Then you then see a truck fly past, releasing all of these toxins and you realise that’s the cause.

I think this is her best role."
Naga: "She's fantastic."
