Serge Marquand

I first saw this guy in Cemetery Without Crosses. My initial thought was : damn, that is one ugly man.
I know he is in only a handful of Spaghettis (I watched The Specialists last night and Wanted is in my stack of movies to watch) but I am curious about him.
Anybody familar with his non-Spaghettis? With a face like that he must have played the villian a lot.
He reminds me a little of Anthony James, the American actor who played the bad guy in lot of films (He played “Skinny” in Eastwood’s Unforgiven).

I know that he was brother in law to Tina Aumont.
