Dawn, who played the vicar Geraldine Granger, also recalled one of Alice’s most well-known and funniest scenes on the show – her I Can’t Believe It’s Not Butter speech.
“She had to learn it a week beforehand and do it again and again and again. But when it came to the day, she did it straight away, word perfectly.
“It’s a speech that if you don’t put the emphasis on the right word, the joke is lost, so she just was genius, absolutely genius, at it.”
The actress led tributes when Emma’s death was announced, posting a picture of her and Emma on twitter saying: “I was regularly humped like this by the unique & beautiful spark that was Emma Chambers. I never minded. I loved her. A lot.”
Dawn isn’t the only co-star to have paid tribute to Emma following her passing.
Hugh Grant, who starred with her in Notting Hill, said he would remember her as “a hilarious and very warm person”.
Meanwhile, writer Emma Freud said: “She was a great, great comedy performer, and a truly fine actress, and a tender, sweet, funny, unusual, loving human being.”
Emma’s funeral will be held this month, with her family confirming the star will be given a private ceremony.
