The degree that these scenes went to... there was a couple of days I was upset... I'd have to hurry back to the girls in the makeup trailer and have a bit of a cry because it messes with your head.

I know the pressures of being the daughter of a great actress. But it's inspiring. You learn so much that other people don't get to learn until later on. My father being a director, I learnt a real work ethic.

I was definitely incredibly close to my dad, in a way that was all-encompassing. I am close to my mum, too, but there were areas that she and I did not share. So his loss to me was huge, personally and professionally. He believed in me, not just as a father, but as a director, and that always meant a lot.

What's in the movie compared to what we shot is the tip of the iceberg.

You can't fake comedy. You can't make it look beautiful or put an interesting bit of music on in the background: funny can only be funny if you're funny.

The thing I thought about doing it was it's Comic Relief and you've got to be funny. So although I did try to sing properly it obviously has hilarious results when you can't sing.

I love doing comedy. But sometimes, that exists at sort of the mid-level to the high-comedy level of craziness, and I don't necessarily get to plumb the depths of kind of serious acting as often.

Same job, whether it's comedy or drama. Regardless of the weight of the role, I feel like the job is always kind of the same. Who is this person? What's this guy here, and how is he playing with this thing, and what's he trying to say? And what's the volley with all these other people around him?
