Born in 1939 in Sofia he was discovered by cult director Binka Zheliazkova and appeared in Metodi Andonov's black and white classic The Goat Horn (1972). Denchev escaped Bulgaria's communist regime in 1978 and continued a multi-faceted carreer in Canada. Declared an "enemy of the people" by the communist government, most of his films and TV shows were banned in Bulgaria until 1989.

Denchev appeared in over 60 films, most of them for children. During the 70's Denchev hosted the daily TV programme Good night, Children. His unique creations were awarded at children's film festivals. His last role in Iglika Trifonova's Investigation brought him back to Bulgaria in 2005.

Memorial services will take place in Montreal and in Sofia.
