I had a great time working with Peter Capaldi on The Hour. I felt such an affinity with Peter. We’d sit on the stairs in our old-fashioned costumes – we both looked extremely old-fashioned, from another world, and somehow I think we felt that. The scene where I told him our long-lost daughter was dead – we stood there looking at each other and we said, this is just so sad. Brilliant writing. Abi Morgan is genuinely interested in middle-aged women, as I am. Often you do a part and think, well this is interesting but not as interesting as my life. Not with this.
