No Greater Love: A rare look at life in a silent order
Notting Hill is a bustling area of London - perhaps best known as the home of the UK's biggest street carnival - but it's also home to a closed religious order dedicated to a life of quiet contemplation and prayer.
Amongst the coffee shops, supermarkets and busy traffic sits the Carmelite Monastery of the Most Holy Trinity, home to a silent order of nuns.
The monastery is so closed off, that even some who live in the same square aren't aware of its existence.
One local resident, Michael Whyte, became so fascinated by the mysterious Victorian building and its silent inhabitants that he decided he wanted to make a film about them.
He started by putting a note through their letterbox but initially received a polite refusal.
He persevered, sending a fresh letter every nine months, then finally ten years after the first approach, the Prioress agreed.
The resultant film - No Greater Love - has just been released and he's been talking to Matthew Bannister about the challenges of making the film and how spending a year in the monastery has changed his life.
