I did some research and SAR/DJ does have a point; the bulk of the Winnetou movies were co-productions with Italy, even though the main contributing countries were Germany and Yugoslavia. Since there is no litmus test to make out if a western is a spaghetti western, we have to rely on definitions; that’s no problem, as long as we realize that they are just that: definitions.
Apparently Weisser counts 558 SWs, using his definition (unknown to me); the Italian writer Casadio counts 451, accepting only those films for which a) an Italian production company was dominant AND b) that were directed by an Italian. Using his definition, El Precio de un Hombre should be excluded. I guess most people wouldn’t agree with that. I like Casadio and his book, but to me EL PRECIO is definitely spaghetti, albeit paella. But paella is no spaghetti, so we’re in that grey area here.
Personally, I don’t think of the Winnetou movies as spaghetti westerns. They certainly created the cultural context in which the spaghetti western could flourish, but I think the feeling is completely different. Old Shatterhand (let alone Winnetou) cannot be imagined in any sort of western made by a italian director and produced dominantly by an italian company between '64 and '70, not in a revenge movie, not in a Civil War movie, not in a Gold Rush movie, not in a Mexican Revolution movie. The only character from the Winnetou films that has some spaghetti value (if I may say so) is Sam Hawkins, in the books Shatterhand’s teacher, in the films more his side-kick.
But this is all very personal. If SD wants to include some Karl May movies, that is his good right.
Still: please SD, take it easy (Eagles, not too loud), we’re talking about people’s lists of favourite films, not about possible reasons to risk WW III or anything like that. It’s supposed to be fun out here.
I think the problem is academic anyway, since few people will include the Karl May movies, so they most probably won’t ever make it to our common Top 20.
