"It's a big chip on my shoulder that I have not been to any of his parties - P. Diddy, Diddy Puff. Bu..." — Emily Blunt

The performances I enjoy are the ones that are hard to read or ambiguous or left-of-centre because it makes you look closer and that's what humans are like - quite mysterious creatures, hard to pinpoint.

I can understand there are things like shadows they need to fix after a shoot, but it's unfair to represent an image of yourself if it's not true. They're gonna see what you look like on film anyway, so why try to cover all your wobbly bits in a photo?

If you're very open to watching the world go by, with people's different tics, you absorb it all without realizing it and find ways to put something into your character. I'm not sure I'm always aware I'm mimicking someone.

I'm Sudafed-ed up, but it's alright because I'm having to do this rather sultry scene, so maybe it's OK that my voice is three octaves lower.
