I could never be anyone I've played. I am so not a detective; I can barely get 200 yards from A to B with the help of Google maps, and I am just about the least observant person on the planet, so I never notice what people look like or how they walk or if they're committing a crime in broad daylight.

My make-up call as Cassie on 'Unforgotten' is 45 minutes, and on 'The Split', it's considerably longer. They have to do your hair and your make-up. On 'Unforgotten,' I'm in and out, and I don't have to worry about how I sit for the whole day so as not to crease the clothes.

It's totally different playing a lawyer and a detective.
