Stephen Fry and Hugh Bonneville attended a star-studded service for Paddington Bear author Michael Bond at St Paul's Cathedral.
The celebration of the writer's life was held this morning, after he died aged 91 following a short battle with illness, in June this year.
During a moving service, Bonneville and young Paddington co-stars Madeleine Harris and Samuel Joslin read out messages from fans marking the life of the late British author from around the world.
The actor said: 'As Stephen Fry put it, Michael was as kindly, dignified, charming and lovable as the immortal Paddington Bear he gave us'.
Mr Bond who penned more than 200 books, was also celebrated by his family and friends, with readings and music paying tribute to his life and illustrious career.

Mr Bond's daughter Karen Jankel was among his family members paying emotional tributes, while his executive publisher Ann-Janine Murtagh, also gave a speech.
Ms Jankel described her father as a 'master of one-liners', who could see the humour in any situation and had 'a twinkle in his eye'.
Paddington was 'so real' that the bear was seen as a member of their family and 'an extension of my father, which means he will always be with us,' she said.
Describing how Mr Bond always signed his books for fans even when he could barely hold a pen, she said: 'He respected his readers as much as they did him'.
Ms Jankel said her father's 'friendly demeanour would melt the hardest of hearts', and that 'women had an unfortunate tendency to fall in love with him'.
'Despite this' he 'only married twice' and Mr Bond's widow and his first wife were both at the service, as well as his grandchildren.

Ms Murtagh said that 'increasingly Paddington's character would inform' Bond's own thinking and that he would sometimes ponder business affairs by asking 'what would Paddington do?'
His books 'imbued deeply held values of courtesy, kindness, justice, tolerance, hope and optimism ... often in the form of a small bear with a hard stare', she said, and are 'as relevant today' as they were when he first created Paddington.
'We promise you we will look after your bear', she told the congregation of family, friends, colleagues and fans.'
The Reverend Canon Mark Oakley told the congregation: 'As we remember with fondness the characters that sprang from Michael's imagination and recall their capacity for doing good, so let us give thanks for a bear called Paddington who fitted our world perfectly because he was different.'

As well as friends, family and colleagues attending the celebration of Mr Bond's life, seats were made available to members of the public.
Children's authors as well as book illustrators, teachers, librarians and schoolchildren have been invited.
Speaking after the service Stephen Fry described the tribute to the late author as 'delightful'.
He said: 'I was particularly pleased by the idea that Michael had it in his head, when making decisions, 'what would Paddington do?' I think that would be a good tattoo for all of us.'
Remarking on Paddington's popularity, he said: 'It was the tension between the anarchy and catastrophe that he caused and the fact he was always dignified and on the side of right, of friendship, warmth and family, without being sentimental or nostalgic.'

Mr Bond's first book, A Bear Called Paddington, was published in 1958.
He also created characters such as Olga da Polga and A Mouse Called Thursday, along with a series of novels for adults featuring the detective Monsieur Pamplemousse.
Instead of floral tributes, donations are being given to Action Medical Research.
Mr Bond was involved with the charity for more than 40 years, with Paddington its official mascot.
