Upperseven has some very good element which should have made it a great one. Unfortunately, there is a little too much chatter by our hero Paul Finney, the Upperseven, played well by Paul Hubschmid. It's not Paul's fault that the writers over scripted his part, and other than the Chatty Kathy stuff he does a fine job jumping around as the elite secret agent especially for a 49 year old man. The other stand out's are the three gorgeous lady's Karin Dor, Rosalba Neri, and a smocking hot Vivi Bach who are all great in there collective rolls.
Other then a couple of long scenes including one where Neri sings an interminable and terrible song, which made me believe she deserved her fate, and watching Upperseven taking on and off his stupid masks, the movie is really quite good.
The other blot is bad guy Kobras (Nando Gazzolo) who was not up to par as the evildoer as let's say Adolfo Celi would have surely been.
All in all this one is a good EuroSpy that could have been a great one if a third of the dialog was cut resulting in a 1:20 film instead of a1:43 film. All in all I recommend Upperseven.
