Mirko was born, according to all available sources, on December 11th 1926 in Zagreb, Yugoslavia (now Croatia) and died, also in Zagreb, aged 86, on August 30th 2013.
He was tall and thin with sunken cheeks and large ears, giving him a rather gaunt appearance.
Mirko's known film career begins in 1959 and he would then be working regularly for the next 43 years. In the sixties he appeared in many peplums and westerns that were co-productions with Italy and Germany. From these he seems to be one of the better known Yugoslav actors, this despite many of his roles, even credited ones, being non-speaking parts.
I have found undocumented roles for Mirko in Italian and European co-productions, and since many of his appearances could be classed as those of a generico, there are probably many small uncredited roles to be found.
