Beryl Vertue, executive producer of the BBC hit show Sherlock, received a CBE for services to television drama and teased a little bit about Toby Jones' Sherlock character who was announced earlier in the week.
Beryl is chairwoman of Hartswood Films and worked on programmes such as Jekyll, Men Behaving Badly and the film Tommy.
Her daughters Sue and Debbie - along with son-in-law and Doctor Who writer Steven Moffat - are also in the family business, and she said it was a "particular treat" to work with people she loved.
Toby was revealed on Monday to be playing a villain in the new series of Sherlock, opposite Benedict Cumberbatch and Martin Freeman, and she said he had already made an impact.
She said: "He's quite chilling, with his seemingly benign demeanour. He is a brilliant actor, and we are blessed really with such fine actors."
She would not be drawn more on the character but said: "It is a very important role. He said to me, 'the minute I read the script I thought I'll have to do this'.
"I think that's a lot of our success - they are so well written. And we have been blessed by actors who can really, really act. Benedict was the only person we saw for Sherlock when we were casting."
The new series of Sherlock is the fourth, and Ms Vertue said she could see it going on into a fifth and beyond.
And she revealed the show's leads had become such big stars that they have to have security keep fans away when they are filming in London.
She said: "They find out where you're shooting, it's like a network and off it goes. They're very well behaved but they come from abroad - a lot of them come from China and Russia, and they bring little gifts with them.
"It's lovely - they make little things, it's so sweet."
