Mirko Valentin was a small-part actor, active in Italian films at least throughout the 1960's.
No biographical details are currently known.
Mirko's facial features - large nose, prominent teeth, hollow cheeks - combine to give him a rather unique look which was exploited to good effect in several horror films. I have previously found several undocumented roles for Mirko, with more uncredited background parts recently appearing via our peplum film topics. It therefore seems highly likely that there will be more roles to be found.
