I had been aware of Zdravko for some time as an unidentified actor from a number of peplum films, but had little hope of identifying him since they were all roles in films shot in Yugoslavia. I got lucky when I spotted him in a small credited role in La strada lunga un anno while searching for images of Niksa Stefanini and was able to confirm his identity from several very helpful videos on You Tube where he is identified. It appears that from the late sixties he worked more as a specialist in special effects and pyrotechnics, a field in which he has a number of credits, but he still continued to act occasionally as well.
No biographical details are currently known, though from his name and career I would think it highly probable that he was Croatian.
Since I first identified him in uncredited roles which do not appear in any of his internet filmographies then I think it is extremely likely there will be more roles to be found in films shot in Yugoslavia.
