British surrealist Leonora Carrington worked alongside Max Ernst, Andre Breton and Pablo Picasso in Paris at the height of the surrealist movement - yet ended up virtually unknown in Mexico City. Now, after her death, her influence is spreading again and biographer Joanna Moorhead and executive producer Angus Macqueen talk to BBC commissioning editor, Emma Cahusac about her incredible life story, their fascination with this extraordinary artist, and how they brought her work to life for this film.  Featuring clips from the forthcoming documentary and followed by Q&A.

The Lost Surrealist is an Erica Starling/Ronachan production for BBC Four
