Kerwin Mathews is Clint de la Roche, le Vicomte (what a name - I'll just refer to him as Clint from now on). Clint is an insurance investigator out to find the loot from a recent robbery. His investigation leads him to Paris where he finds himself caught between two rival gangs. He also finds himself entangled with a Parisian stripper who may or may not have information he needs. You know, your standard Eurospy plot.
The Viscount isn't the best Eurospy I've seen, but it's not a complete waste of time. Mathews is quite good and has a real screen presence. Other cast members that stood out to me include: Sylvia Sorrente (the stripper), Fernando Rey (gangleader) , and Jean Yanne (Cilnt's "assistant"). The film features plenty of reasonably entertaining fight scenes, chases, and gunplay - again, pretty standard Eurospy stuff. The robbery at the beginning of the film is especially nice. It's well planned and expertly carried out. It's a real highlight of the film. I was going to write about some confusing elements of the plot, but, instead, I've decided to blame the issues I have with the plot on my lack of foreign language skills. (The copy I watched had some scenes that were not dubbed - and the subtitles made things even worse.) The film's ending was something of a letdown. The final scenes are, unfortunately, set at night and it's about impossible to tell what's going on. Overall, a fairly average film that I can honestly rate no higher than a 5/10.
Oh, one last thing - I forgot to mention the incredibly entertaining 60s vibe found in The Viscount. The music, locations, costumes - it really pulls you into the time period. Very nice.
