Giovanni Bonadonna was a stuntman and actor who was active in Italian films from at least the start of the 1960's until the early 1980's.
He was the brother of stuntman Elio Bonadonna and the brothers often appeared in films together. No biographical details are currently known.
While I have found a few early peplum roles for Giovanni, his 60's and early 70's filmography is still rather sparse, so I'm certain there must be more roles to be found, almost certainly some more westerns. In the mid-late 70's he maintained a dark goatee, giving him a more distinctive, somewhat-Arabic look.
In addition to his film work, Giovanni was also very active in fotoromanzi, and from 1966 to 1971 and again from 1974 to 1975, he appeared in a significant amount of fotoromanzi for the well-known publisher Lancio He specialized in playing henchmen, thugs, cops or other parts that required some physicality, and was either credited as Gianni Bonadonna or went uncredited. After leaving Lancio, he began to appear in fotoromanzi for rival publisher Condor in 1976 and continued to appear in these until Condor ceased production in 1981. He played mostly the same kind of roles here, but was also awarded larger, more comedic character parts. His brother Elio also appeared alongside him in fotoromanzi, but only very occasionally.
