She was a joy to write for, subtle, many-layered, intelligent, funny and heart-breaking.
Working with her has been the greatest privilege of my career, and I will never forget her.
I feel tremendously lucky to have known such a maverick.

She will be deeply missed and my thoughts are with her family.
She was a true legend of her generation and thankfully will live on in so many magnificent screen performances.
My condolences to her boys and wider family.
Joanne Froggatt, who played Anna Bates, payed tribute to Smith on Instagram.
Today we lost a true legend.
Its hard to find the words to pay tribute to the iconic Dame Maggie Smith.
There is only one Maggie Smith and she will be greatly missed.
