Found a review of this five-part 1976 Italy/UK miniseries (co-produced by Radiotelevisione Italiana and ITC) at DVD Talk. Has anyone seen this? Did it ever air in the US? Judging from this cast, it looks to be the IT'S A MAD MAD MAD MAD WORLD of mid '70s EuroCult, including the final performance of the great Lee J. Cobb (this aired in Italy several months after his death). With a retail price of $19.99, I'm picking this up just for the historical value of all these actors in the same project.
