Sometimes when a scene is written or directed to be shouted or played incredibly angrily, I always think it's way more terrifying when someone is fuming and talks in a very calm way. I always want people to shout at me if they're angry - it freaks me out that whole thing of, 'I'm not angry I'm just disappointed.'
I shout at the radio when someone starts talking over the end of a song. Shut up! I don't want to hear that the DJ has just found a mouldy sandwich in the corner of the studio. Nor do I like it when the magic of something you're watching is shattered by an advert for Argos.
I filmed 'Albatross' before I got 'Downton.' It's a coming-of-age movie about this girl who leaps into this family's life, like a whirlwind. She's ballsy and brash and wonderful, it was such an amazing character to play.
On the surface, it's really easy to dismiss certain characters, but sometimes you find that the most interesting parts are disappointingly shallow. It's your job as an actress to pull that person apart, and work out why they act the way that they do.
The first episodes I actually read for 'Downton,' Sybil was really intimidated and hadn't come into her own. So it's only in Series Two that she's become so headstrong. In general, I find it exciting to play strong, female roles because they're shocking.
I'm starting to shake it off, I am quite self-conscious, and it's only when I'm playing roles that I can escape that. The older I get, the more people tell me it's absolutely fine to be the way you are with all your quirks and nuances, and I wish I'd learnt that younger - I would have relaxed a bit more.
We filmed 'Labyrinth' in South Africa for two and a half months and it was just the most unbelievable experience. Lots of sword fighting, mud in hair and lots of weeping! It's very different from 'Downton' because I was going to work and having mud put in my hair - it's the other extreme of the look!
I like to accessorise shirts with a little ribbon tied round my collar or a country style ascot. I've also sewed little hearts on some of my sleeves which I've done for years because I always wear my heart on my sleeve so if you see a little embroidered heart on my clothes, that's why!
