 While working in Warsaw Belyavsky learned the Polish language and later appeared in five more Polish films, including the popular TV wartime thriller series "The Four Tankmen and a Dog" (as a Soviet captain Pavlov).In 1964 he left the Satire Theatre but never severed ties with its troupe, having become the co-director (with Georgy Zelinsky) and the first presenter of the popular TV series "13 Chairs Tavern".It was Belyavsky who came up with the idea of staging a satirical TV series ridiculing a good-for-nothing 'firm' (apparently based in Poland), members of which meet at the tavern to discuss their (highly ridiculous) problems and perform Polish (later West European) pop songs in a karaoke-style.
