BBC has produced documentary on early 20th century British Muslim Converts. Documentary sheds light on lives of three prominent converts: William Abdullah Quilliam, Lord Headley, and Marmaduke Pickthall. Film also shows scenes of Shah Jehan Mosque/ Woking Muslim Mission. At 14:19 it looks like Maulana Sadar ud Din is delivering lecture.
One think thing that disappointed me is comments by Humayun Ansari, Professor of the History of Islam, Royal Holloway, University of London. Professor Ansari has distorted history just to hide the Lahore Ahmadiyya Movement connection with three Muslim converts in documentary.
I would suggest this documentary is stored in Woking Muslim Mission website maintained by LAM, UK.
