With the exception of the opening sequence, a scene in Garko's mansion, Klaus Kinski's minimal participation and Garko himself there isn't much to watch here.
Slow and plodding.
The first Silver movie with Peter Lee Lawrence is much better.
EDIT: I will add that seeing all the back alleys at Elios studios is a real treat.
You don't see those too often and puts to rest whatever rumors there were about the buildings being simply facades.
