Barabba (1961) as Gladiator.

Not too clear due to him being in the background and moving, but based on the way he looks in Ercole alla conquista di Atlantide the same year, plus the fact that brother Elio is in the same scene which seems to be a good indicator, I think this should be Giovanni on the left (he seems to be fighting an invisible opponent!). I would call it a probable ID rather than uncertain.
