Harry Potter author JK Rowling and actor Eddie Redmayne have arrived in Leicester Square ahead of the premiere of Fantastic Beasts And Where To Find Them.
JK looked glamorous in her gold dress on the carpet - which had been turned blue for the occasion.
The film is based on JK's book of the same name and is set 60 years earlier than the novels about the boy wizard, in 1926 New York.
In the film, Eddie plays "magizoologist" Newt Scamander as he explores the American branch of the magical world, with a mysterious suitcase full of magical creatures.
The rest of the film's cast also walked the carpet including Ezra Miller.
Also attending were McFly's Danny Jones, Tom Fletcher and Harry Judd.
Game Of Thrones actress Maisie Williams also attended the premiere as did Guy Ritchie and wife Jacqui Ainsley.
Also gracing the carpet was the latest Strictly star to leave the show, Daisy Lowe.
Daisy was joined by professional dancers Aljaz Skorjanec and Janette Manrara.
