The Mosque sees filmmaker Robb Leech gain unprecedented access to Britain’s biggest Muslim community, to capture a unique insight into the world behind its walls and the people who make up its congregation. East London Mosque is the largest in Europe. Over a quarter of a million people walk through its doors on the Whitechapel Road during the month of Ramadan, and five thousand fills its walls for Friday prayers. It’s the central hub of East London’s Muslim community. Yet for many outside, it’s a place of mystery and the unknown. Director Robb Leech first followed his step-brother Rich and his conversion to radical Islam, in My Brother The Islamist (2011), and its sequel My Brother The Terrorist (2014). In this new film, Robb will explore ‘everyday’ Islam in Britain, meeting its people and experiencing their faith at first hand. Robb’s distinctive hand-held camera style gives a very personal feel to the documentary; this proves key as Robb captures the first emotional encounter between the Mosque’s charismatic young communications manager Salman and a distraught sister of one of the three Bethnal Green schoolgirls who flew out to join ISIS jihadists in Syria.
