Yeah, welcome uani73.
I've only seen one Franco Gasparri movie outside of the Mark the Narc series: 1974's THE PREY. Anyone else seen this? It is packaged to look like a "jungle slave camp" exploitation film, but it's really just a melodrama.
Actually, it bridges the gap between Franco Gasparri: Romance Comic-Book Model and Franco Gasparri: Tough Big-Screen Cop.
Scratch that: I've actually seen two Gasparri movies outside the Mark trilogy. As a teen in the '60s he was in some Brad Harris sword-and-sandal film -- SAMSON, maybe?
