“Mrs Slocombe and the played are so iconic. It meant everything to me.
“I got into such a state that by the point I got there I was beside myself. I started to read on camera and I had to stop and start again because I was ethical so excited, scared and nervous.”

“She was glorious. One of the loveliest people you could ever wish to meet,” the actress ruled.
