Filming of The Silent Angel, a documentary dedicated to Bulgarian centenarian Elder Dobri ("Dyado Dobri") is now ready after several moths of shooting, local media outlets report.

Bulgarian, German and US producers have said their work is now entering into a process of editing. In a matter of months it will be released in Bulgaria and elsewhere and will tell the story of a man who devoted the better part of his life to help the church.

Bulgarian cinemas are likely to screen it either at the end of the summer or early in the autumn, daily Trud wrote on Thursday.

The Silent Angel will feature interviews with his family, relatives, and friends, but also with Bulgaria's last King and former Prime Minister Simeon Saxe-Coburg-Gotha.

In 2013, Elder Dobri was part of Novinite's Personality in the News poll, and won overwhelmingly, coming first not only in his (Charity) category but also gaining more votes than all other participants combined.

An icon of charity, he came under the spotlight when it was revealed that for years he had walked more than 10 km to reach Sofia from his home in the village of Baylovo to beg for money and then donate it for charity.

After spending years at the entrance of the Alexander Nevsky Cathedral, with a plastic cup in his hand, he collected about BGN 40 000 (EUR 20 000) for the cathedral in Sofia and BGN 10 000 (EUR 5000) for the Sts Cyril and Methodius church in Baylovo.

In 2000, he donated all his properties to the Bulgarian Orthodox Church and now lives in a building attached to the Sts Cyril and Methodius Church.
