Under the Roofs and in 1968 in The Dead Season. In 1969 he starred in Tomorrow, April 3 and The Ugryum River. In 1971 he starred in Dauria. In 1972 he starred in Hello and Goodbye and The Singing Teacher. In 1973 he once again reunited with Leonid Gaidai to star in the film Ivan Vasilievich: Back to the Future where he played a scientist named Shurik who invents a time machine. Demyanenko was unable to gain popularity for other roles as he was typecast as a scientist due to his tremendous popularity as the nerdy, crime-fighting student Shurik. He frequently provided voice-overs for foreign and domestic films, and even Donatas Banionis admitted that his dubbing was an improvement over his original acting. Later years He appeared in the television movie Old Songs of the Main Things 2 in 1997 playing an aged Shurik. He had a brief role in the TV series Strawberry and reprised his famous role of the nerdy professor in Old Songs of the Main Things 3 in 1998. He was diagnosed with congestive heart failure but was afraid of getting bypass surgery. In 1999 Aleksandr Demyanenko died from a heart attack. Some analysts say this played a part in the success of the Communist Party of the Russian Federation in the December 1999 elections as the lack of a social welfare system was frequently blamed for his death. Personal life His first marriage was to Marina Sklyarova with whom he went to acting classes. He divorced Sklyarova when he became involved with voice-over director from Lenfilm Liudmila Demyanenko. She became his second wife and they remained married until his death. He became the stepfather to her daughter Angelica Nevolina, who later became an actress.
