Tributes paid to 'true legend' Dame Maggie Smith
Tributes have been paid by the King and prime minister, as well as numerous co-stars from her long career.
King Charles described her as "a national treasure", while Sir Keir Starmer said she was "beloved by so many for her great talent".
Harry Potter star Daniel Radcliffe fondly remembered her "fierce intellect" and "gloriously sharp tongue".
Miriam Margolyes said she was "the best of the best", who combined "ferocity, a glint of mischief, delight and tenderness".
"And enormous courage. I've been in awe of her, as all her colleagues are," Margolyes told BBC News.
"I saw what a kind person she could be - as well as absolutely terrifying."
Paying tribute, Radcliffe said: "She was a fierce intellect, had a gloriously sharp tongue, could intimidate and charm in the same instant and was, as everyone will tell you, extremely funny.
"I will always consider myself amazingly lucky to have been able to work with her, and to spend time around her on set.
"The word legend is overused but if it applies to anyone in our industry then it applies to her. Thank you Maggie."
Emma Watson said she didn't quite appreciate that young Hermione was sharing the screen "with a true definition of greatness" until her adult years.
Posting on Instagram, she remembered the star for being "real, honest, funny and self-honouring".
"Maggie, there are a lot of male professors and by God you held your own."
In a statement, the King and Queen said: "As the curtain comes down on a national treasure, we join all those around the world in remembering with the fondest admiration and affection her many great performances, and her warmth and wit that shone through both off and on the stage."
The prime minister agreed that Dame Maggie was "a true national treasure whose work will be cherished for generations to come".
She "introduced us to new worlds with the countless stories she acted over her long career", Sir Keir said.
Hugh Bonneville, who played the Earl of Grantham in Downton Abbey, said: “Anyone who ever shared a scene with Maggie will attest to her sharp eye, sharp wit and formidable talent.
"She was a true legend of her generation and thankfully will live on in so many magnificent screen performances."
