Khan Asparuh is a 1981 three-part Bulgarian historical action and drama film telling the story of Khan Asparuh and the events around the founding of the medieval Bulgarian state in 681 AD. It was shot and released on the occasion of the 1300th anniversary of Bulgaria. The film was selected as the Bulgarian entry for the Best Foreign Language Film at the 55th Academy Awards, but was not accepted as a nominee.
The director is Ludmil Staikov, with Stoyko Peev playing Asparuh, Antoniy Genov playing Velisarius and Vanya Tsvetkova Pagane.
In 1984 the film was internationally released as 681 AD: The Glory of Khan in a 92-minute English-language edited version, down from the original 4½ hours. The version has received much criticism for not presenting the entire plot well and focusing on certain aspects, thus changing the whole feel of the production.
