One of his leading roles in cinema was O Kyr Giorgis Ekpaidevetai (Mr. Giorgis is being educated) (1977) which was the last film made by Finos Film and marked the end of an era. He also worked for television. One of his biggest successes was his role once again as Mr Giorgis for the television show Louna Park. He was generally considered as an actor with an enormous talent and incredible acting techniques. He always left a strong impression in all the roles he had, comical and dramatic. Remarkable was his work in the play To Megalo mas Tsirko by Iakovos Kambanelis, in which he portrayed Theodoros Kolokotronis, Eleftherios Venizelos and Karagiozis.

He died suddenly at the age of 71, in his apartment on Alexandras Avenue, today to the Metro Station Ampelokipoi region, due to a stroke. The people of Diakopto erected a statue in his memory, although, during his life, some had opposed him due to political issues.
